Q:
Hey Todd, I recently had a Bob's Machine Shop exhaust tuner installed
in my |
| 93
150 XR6 Merc |
'93 XR6. This took my rpms from
58-5900 to 6100+ (6000 rpm tach pegged hard) |
| |
and added another 3.9 mph on top end.
This setup gives me 69.3 mph (Garmin |
| 25"
Tempest |
GPS12) at well over 6000 rpm. I'm not
sure what top end rpm is on my engine, |
| 6"
jackplate |
(bought used, no owner info). I would
feel more comfortable at around 5800. My |
| 3"
off transom |
question is if I pitch up to bring rpm
down, what would likely happen to my top |
| 69.3
mph @ 6100+ |
speed? Also, what is your
opinion of running an XR6 over 6000 rpm? Do you |
| 21-22#
psi |
think any other prop could be faster
than a Tempest on this boat? More info on my |
| |
boat can be seen at the Ranger Owners
lists. Any other tips you might wish to share |
| |
would be greatly appreciated. |
| |
A:
You have cured what Merc does to make a 150 a 150....relieved the
exhaust... |
| |
Bob's has a good tuner, in fact I ran
a Bob's on a Mod VP at 350 HP for a while |
| |
and was very happy with it.
Usually the cost of the Bob's tuner is a reduction of |
| |
low end torque...causing a small loss
of holeshot. |
| |
The 150 XR6 is rated at 5500
redline....it will spin more but it makes no power past |
| |
about 5700 with the exhaust
restrictions it has...restrictions you have done away |
| |
with...so I think 5800 rpm would be a
very good range to operate in....... |
| |
the 27 Tempest should drop r's to
5700....and upping the pitch is going to up speed |
| |
also...even with the reduction of
rpms....In all honesty, I'd give the new 26 Tempest |
| |
a try....it has been doing very well
on the 20' Tritons with 225's and should do |
| |
well on your 364. |
| |
The 26 should put you to 58-5900 and
over 70 mph....I'd give a 26 Trophy a try |
| |
also....even tho I like the 3 blades
on the 3 Series Rangers....you're running very |
| |
well. A little more positive
trim on the XR6 with extenders and possibly a little |
| |
bigger jetting may be
necessary...relieving the exhaust may have you running a little |
| |
lean right now. |

Q:
Interested in buying this boat. Has torquemaster lower unit with
2:1 gears |
| 98
200 Merc EFI |
and 27" 3 blade prop. The
boat has a terrible holeshot. Top speed with no gear, |
| |
2 people and 1/2 load of fuel was 60
mph. My apologies for the lack of technical |
| 27
Tempest? |
info. What prop should this boat have
(for best all around performance), considering |
| 60
mph @ ? |
the 2:1 gears? What top speed
should I expect? Thanks........ |
| 15#
psi |
A:
I'm trying to imagine how a 2:1 torquemaster made its way on a 200 2.5
liter... |
| |
If it didn't have the 2:1 ratio this
is what it would run......25 Trophy (5 series likes the |
| |
4 blades) in the second hole from the
top for about 65-67 mph gps....add a 6" plate |
| |
and it's 67-69 mph. |
| |
The 2.5 EFI will spin 6K....my 200 EFI
on the 518 ran 70 at 5750 with a 25 Trophy |
| |
.....so this is what I think.....run
the 25 Trophy to 5900 or 6000....if it spins higher |
| |
than 6000 go to the 26 Trophy....it
will be faster anyway. Start pulling PVS plugs |
| |
with the Trophy till the holeshot gets
where you want it. |

Q:
I recently swapped from a Laser II to a Tempest Plus. It improved
everything |
| 95
175 Merc EFI |
except now my boat chinewalks
terribly. Everything is tight (steering, plate, so on). |
| |
I usually fish alone & carry a
light load. Do you think raising my plate will help the |
| 25"
Tempest Plus |
chine? Or should I lower it?
Like everyone else I would like to peak performance |
| 6"
jackplate |
out of my boat, but do not want to
give up overall performance to get top speed. |
| 3.5"
below pad |
Do you have any setup tips to help cut
down the chine? Thanks..... |
| 62
mph @ 5400 |
A:
You probably need to lower the plate...Rangers only get worse with
height. |
| 15#
psi |
I know you're having control problems
right now....but....the 175/360 series hull |
| |
is a potent combo...you have the tools
to go almost 70 mph....make sure your |
| |
weight is decently balanced...as in
most weight to the rear and passenger side. |
| |
This will help reduce chine also.
A trip with an experienced chine walk driver to |
| |
show you some steering inputs will
make coping easier. |

A:
You're gonna have to experiment....the L2 ain't bad for small
boats......don't |
|
Laser II prop
|
be afraid to try aluminum also....put
your hands on everything that will fit the Merc |
|
48 mph @ 5400

and try it....keeping a log of results
of course. |

Q:
My holeshot is great. Is there anything I can do for more top
end speed? |

I am thinking of going to a 175 EFI.
What would you think this would do to the |
| |
top end? |
| 23"
Trophy Plus |
|
| 6"
jackplate |
A:
All the 370's I've dealt with using 175 power ran low mid
60's....swapping |
| 3
1/4" off transom |
to a 23" Tempest will probably
give 2 more mph on the 375...60 should be close |
| 56
mph @ 5600/5700 |
to max for the 150. |

Q:
Hi Todd, You have been very helpful in the past. I have a simple
question. |
| 00
175 Merc EFI |
I maintain my engine and have just
winterized it. This is my first EFI engine. |
| |
In the owners manual for winterizing,
it states to put fogging oil in to the spark plug |
| |
openings. All my other engines I
was able to do this through the carburators. |
| |
Also I used Engine Tuner every other
year on my past engines. My question is this, |
| |
is there any other way to fog and use
engine tuner on these EFI engines? |
| |
Is there some type of port that I am
missing? Is it safe to use engine tuner on an EFI |
| |
engine. These engines cost way
too much money for the average guy to neglect. |
| |
Thank you for your time..... |
| |
A:
Your EFI has throttle blades on the backside of the airbox....spray
your fogging |
| |
oil and tuner in here while the engine
is running....also....it is imperative after fogging |
| |
the engine while running, to spray the
fogging oil into each plug hole while the engine |
| |
is off....spin it over with the oil in
and plugs out....install the plugs and put it up.... |
| |
fuel stabilizer run through the system
is the most important part of winterization in an |
| |
outboard tho..... |

Ranger R81 |
Q:
I feel the boat should be turning more rpm. The motor is in the
next to the |
| 99
175 Merc |
last hole (factory setup). I
moved it to the last hole and gained 3 mph and 300 rpms |
| |
but lost water pressure (below 10#).
I moved the motor back to the stock |
| 25"
Tempest |
location. I was loaned a 24
Trophy small hub. I could turn it 5900 rpm with good |
| 62
mph @ 5200 |
water pressure but could only get 60
mph. I had some bow lift but not what the |
| 14#
psi |
25 Tempest gives me. Any
suggestions would be helpful. |
| |
A:
A couple of solutions....add a jackplate.....you'll be
happy you did. Or....add |
| |
pipe plugs to your intake ports in the
lower unit so you don't draw air in while |
| |
mounted in the top hole......or add
the torquemaster style inlet scoops. |
| |
If you pipe plug it do only the top
hole and then run it....if 10# or better go with it..... |
| |
if under 10# still add another set of
plugs for a total of the top 2 holes plugged. |

Q:
My rpms are too high. Hole shot is OK with plugs out. We
put in on the q |
| 02
225 Merc |
computer to check rpms and I have gone
over for a few seconds. I can't give it |
|
Optimax |
full throttle on calm to slightly
choppy water; typically in the morning because the |
| |
warning bell comes on because of too
high of rpms. |
| 25"
Tempest Plus |
EVERYONE says the 25" is what it
should be but I can't get it to work. What size |
| 6"
jackplate |
prop would you recommend? I
thought about a Yammie or a 4 blade Powertech. |
| 65-69
mph @ |
Do you think it's possible to run a 26
or 27 pitch with proper vents to get holeshot. |
| 5900-6000 |
I usually run the Bob's hydraulic
plate at about 1" on the LED; anywhere else and |
|
25-30# psi
|
it beats you to death or doesn't run
right, with rpms/water pressure. |
| |
I have a 23" or 25" Raker
and a 25" Renegade; would be willing to work something |
| |
with those for another prop.
Also how much would it cost to go over the setup |
| |
with someone and get the right props;
where could I go to test props? |
| |
A:
I'd put a 26" Trophy on it now....5750 is redline and most
Opti's limiters |
| |
would have kicked in long ago. |
| |
Still with a 1.7:1 gear ration and a
25" Tempest you should go well over 70 gps. |
| |
I think you may be jacking a littly
too much with the hydro plate....it's losing its |
| |
efficiency somewhere. |

Q:
Do you have any suggestions on how to get a little more top end out of
this boat? |
| 99
175 Evinrude |
I am running this boat at an altitude
of 6500 feet with this setup and maybe I can't |
|
Ficht |
get any more out of it than I am now.
I am getting some bow lift, and my holeshot |
| |
is OK. It came with a 25"
Renegade originally, and I couldn't get any speed or |
| 24"
Raker |
rpms out of it. Other than the
top end, I am very satisfied with the boat, not real |
| 5"
jackplate |
happy with Evinrude, but that's
another story. |
| 3.5"
below the pad |
A:
Well....there's no shame in having to run smaller pitch props
at 6500 feet....... |
| 55
mph @ 5400 |
and I'd recommend dropping to a
22" Raker....a 23" Renegade will spin the same |
| 20#
psi |
as the 24" Raker due to added
drag from the extra blade...but may give more lift |
| |
if needed. |
| |
The 175 is rated for 5800....and I
think you need to get as close to redline as |
| |
possible to make as much power as the
severe altitude will allow. |
| |
The boat you have with the Ficht is a
65 mph boat when properly rigged at sea |
| |
level.....so if you can even approach
60 I'd say you're doing well. |

Is the 63 mph speed that I'm getting
about all I should expect out of this boat? |
| |
Thanks for any info...... |
|
25" Tempest
|
A:
Before we get into plates, do this.....borrow a 24" Trophy
and run it....the 25" |
|
63 mph @ 5400
|
is too big for the 175 and the Tempest
isn't the prop for the 5 series...the Trophy is.... |
|
|
the 24" should get you to 65 and
55-5600 rpms....give this a try and write me back.. |
| |
I've run several 4 and 5 Rangers also. |

Ranger 520dvx |
Q:
What is the ideal "all-around" prop for this boat? I'm
running the 24" Raker now, |
| 01
225 EvinRUDE |
and the handling/holeshot is awesome.
With tournament load and 1.5 tanks of gas, |
|
RAM |
I ran 68 mph on gps....but rpms are
maxed out at 6000. I'd like to hit the magic |
| |
70 mph mark with full tourny load
while keeping the holeshot and handling while |
| 24"
Raker |
not exceeding 6000 rpm. What do you
recommend? |
| 68
mph @ 6000 |
A:
The other 5 series boats like the 4 blade better....but I have
had no dealings |
| |
with the 520 wo we'll have to do some
common sense testing. |
| |
In theory a 4 blade will spin the same
rpms as a 3 blade that is 1" pitch bigger.... |
| |
i.e., the 23" 4 blade will turn
what the 24" 3 blade will turn....so if we lose 200 rpms |
| |
per pitch size your would do well with
a 25" Raker....but they don't make one...so.... |
| |
the next choice would be the 25"
Renegade....but that should cost 300 rpms....200 |
| |
for pitch enlargement and another 100
for the 4 blade design. |
| |
I'd like to see you stay in the 5800
range....and you're running very well with the |
| |
big Ranger...so.....I suggest a
25" Merc Tempest.....it should run a 5800 and is a |
| |
faster prop than the Raker....plus it
is a common prop and can be found easily. |
| |
The addition of a Merc to OMC
FloTorque hub kit will let you run all the new Merc |
| |
props you want.... |
| |
The 26" Raker will cost 400
r's....the 25" Renegade will cost 300....the 25" Tempest |
| |
will cost 200....all will add speed
and reduce r's. |

Q: This
is a boat I am purchasing from the dealer. It was a demo boat. The
dealer |
| 00
225 Merc |
has GPS'd it running at 70 mph. My
question to you is, do you think that adding |
|
Optimax |
a jackplate to this hull/outboard
combination will do anything to increase its |
| |
performance? I'm wondering if
the added expense of a jackplate will payoff in an |
|
70 mph
|
additional 3-4 mph. I would like
the ability to play with engine height/prop |
| |
combinations that a jackplate would
allow. What do you think? Thanks in advance. |
| |
A:
I used to fish for Ranger....have run several....if that boat
will do 70 don't change |
| |
a thing! But.....it won't.
It may show 70 on the speedo but it will run more like 66 |
| |
on the GPS. It's an excellent
boat....and I have never fished from a more stable |
| |
platform......but if you're buying
based on 70 mph performance and the hopes of |
| |
getting more I'm afraid you'll be
disappointed. |
| |
I'm not always right.....it's there
and I'm here.....but I'd make the dealer show me |
| |
close to 70 on the gps first if 66
isn't enough. |
| |
If you do get it....and then want to
add the plate I don't really think you'll see more |
| |
than 1-2 mph.....wherever you are now. |

Q:
I am currently in the process of buying the R71 Ranger that has a
24" Laser II |
| 01
125 Merc |
on a Merc 125. Is this the best
prop for this rig or would a Trophy perform better? |
| |
I'm looking for total performance and
definitely don't want to get crazy with the |
|
24" Laser II
|
rpms with this four cylinder.
Thanks in advance for your response....... |
| |
A:
The Laser II isn't that bad on smaller boats.....but....I'd go
Trophy.....speed |
| |
may be about the same.....holeshot may
be better on the Laser II.....but all around |
| |
the Trophy will win out. |

Q:
I am looking for the best setup for my boat as it sits. I plan
on finding a 175 for |
| 94
150 Johnson |
it but currently I'll have to work
with what I have. I have also tried a 25" Renegade |
| |
that got 56.3 mph @ 4900 rpm.
Would a 24" Tempest gain me any performance? |
| 23"
Renegade |
Or what setup do you recommend? |
| 57.5
mph @ 5400 |
A:
You've got one of my top 5 favorite boats of all time....with
my 15th or so |
| 23#
psi |
favorite engine.....the 461 needs a
200......will live with a 175 (I've had 2) and |
| |
struggles with the 150's. |
| |
In all honesty the 4's like the 3
blades.....especially the Tempests by Merc....I think |
| |
a 22 Raker would do ok and get you in
the rpm range you need to be in.....look for |
| |
62 mph when right....maybe 64.
The 23 Tempest by Merc would do best by far..... |
| |
but probably won't be a lot
faster.....just better all around.....to save buying the |
| |
Flo Torque kit for OMC try a 22"
Raker first......and leave the 4 blades alone on the |
| |
461.....I've been there already. |

Q:
I just purchased this boat from an elderly man and the boat looks like
new. |
| 86
XP150 Evinrude |
The motor was 1" off the transom
and no jackplate. The boat would barely run |
| |
50 mph and would only turn 4800 rpms.
I know I am not picking the best time of |
| 24"
Raker |
the year to get good performance; the
heat index has been 100 to 105 and the water |
| 6"
jackplate |
temp is in the low 90's. I put a
6" jackplate on the boat and have had the motor |
| 4"
below the pad |
from 3" below the pad to
4.5" below the pad. I ran a compression check on the |
| 53
mph @ 5000 |
motor just to make sure it was not
weak and all cylinders were 105 to 110. I know |
| |
this boat should run at least 60 or
so. I have called around and the 24" Raker prop |
| |
seems to be a common prop for the 3
series Rangers with OMC 150's. |
| |
The prop seems to be in good shape
with only the normal little nick here and there. |
| |
A:
4.5" is WAY too low. 3" should be close.....but
you probably need to come up. |
| |
The 24" Raker would be what I'd
recommend. |
| |
If the boat has sat any length of time
you may be due for a carb job. It may need |
| |
an impeller also......I'd install one
for insurance anyway. |
| |
I'm not an XP/GT fan at all.....but
the 350 is a runner and should do upper 50 to 60 |
| |
anyway......come on up. |

| 00
150 Evinrude Ficht |
recommendations for setup, i.e., prop,
engine height, jackplate, max rpm. |
| |
A:
I'd say you're going to need a 22" Raker, a 6" plate,
set at 3" under pad to |
| |
start and the rpms to be about
5800......max. Look for low 60's. |

Q:
Is this 27" Yammie prop the best for my setup....I'm not a speed
demon but I |
| 98

do like lift in the mids to upper
mids.....I've been told I should be turnin' a 25" Trophy |
| |
to get the rpm up in the 5600-5800
range....should I have this Yammie prop tuned?? |
| 27"

A:
The 27 is going to be too big no matter what you do.
I'd like to see you try a |
| 6"
jackplate |
25" Trophy.....but at the very
least a 25" Yamaha.....the 25 Yam should get you to |
| 68
mph @ 5100 |

Q:
Tremendous holeshot but lacks top end speed. Propshaft is 29
1/2" down from |
| 97
115 Merc |
transom. I am concerned about
rpms. Engine max rpms should be 5250. Please |
| |
advise if another prop or engine
position should be changed, or jackplate is needed. |
| 22"
Laser II |
A:
5250 is it on rpms. PERIOD! the little inline will come apart
very easily at 5400. |
| 46
mph @ 5400 |
Make a swap to a modern style Trophy
or Tempest in 22" pitch and you'll see an |
| |
improvement in mid and top end
performance.....holeshot may suffer a tad over the |
| |
Laser II......but I think you'll like
the rig better once the L2 is gone. |
| 99
Ranger 518VX |
Q:
I don't think I'm getting the speed or rpms out of my motor that I
should be |
| 99
200 Merc EFI |
getting. I added the jackplate
hoping that I would get more boat lift, speed and |
| |
rpms. Before adding the
jackplate I was running the Tempest Plus 25" and I was |
| 25"
Tempest Plus |
turning about 5700 rpms and running
about the same as I am with the jackplate. |
| 6"
jackplate |
By adding the jackplate my rpms
dropped with no speed change. I have tried the |
| 67
mph @ 5300 |
25" Yamaha with a loss in speed.
I also tried a 23" Tempest Plus with not much |
| |
results. I adjusted the
jackplate with all of the props. I thought about trying a Trophy |
| |
prop. If you can please tell me what I
can do to get the most out of my motor. |
| |
I know that Rangers are not as fast as
a lot of other boats but I was wanting to know |
| |
if I can get more. Do you think
changing the reeds and adding an exhaust tuner |
| |
would help? |
| |
A: I'd
stay away from tuner and reeds....the gain is just not really there on
a heavy |
| |
hull....plus the tuner could
potentially kill your holeshot by relieving too much back |
| |
pressure. The 5's run the
Trophy....the 4's run the Tempests....make the swap to the |
| |
25" Trophy and go through your
jackplate settings again. I think you'll find the |
| |
Trophy to be better. |
| |
In the South Carolina heat don't look
to break 70.....when it cools 71-72 is possible. |
| |
My 518 ran 73 one time.....and
68-70 the rest of the time. |

Q:
I had recently talked to you about the 1996 Skeeter I had. I was dead
wrong. |
| 99
175 Johnson |
I told you a speedo speed and I was
way off. It was 8 mph slow. The Skeeter |
| |
ran just what you said it
should....61.6!! Anyhow, the GPS caused me to trade |
| 24"
Raker |
boats. I took a GPS with me to
try the R81 out. Was not impressed at 1st with |
| 6"
jackplate |
the 25" Renegade it had on it.
The dealer put me on a 24" Raker that had been |
| 2.5"
off transom |
worked and it set it on fire.
The boat ran 65.8 loaded with 2 people (gps I might |
| 67
mph @ 5500 |
add). I added a CMC plate last
week and ran it by myself and going by speedo, |
| 27#
psi |
it gained a couple mph but dropped
150-200 rpms. How can it lose rpms and gain |
| |
speed? It also chinewalks badly
now. It reminds me of my Astro F18 I used to run. |
| |
I can drive a high performance boat,
but was wondering do I need to keep raising |
| |
the motor any?? Will this slow the
chinewalk down? Thanks for your help...... |
| |
A:
The Ranger usually gets worse the higher you go. The prop
is now hooked up... |
| |
that's what the clean flow of water
has done to it. It eliminated slip and inefficiency |
| |
as well as lifted the hull to the
point it has to be driven. |
| |
Now this next part is totally up to
you....but if it were me....I'd jack it on up and get |
| |
all the speed I can and learn to
control the chine. My 518 Chinewalked like a big |
| |
dog it was set so high.....but no one
knew because I drove it without chine. |
| |
The combo you have is a nice
rig.....and it's running well....but it can do more. |
| |
You need to find a TR21 owner and
spend a day with them doing some driving |
| |
exercises.....the R81 won't be as bad
as a TR21.....so it shouldn't take long to get |
| |
the hang of it. |

My prop seems to loose grip or blows out of the water when making
turns. |

115 Evinrude |
Evein when the motor is trimmed down.
I am not talking about hard quick turns |
| |
like a ski boat makes, this I could
understand. Would a jackplate help me? I bought |
| 20"
Raker |
this boat new, shortly after I did,
the dealer went out of business. The 115 is the |
| 54
mph @ 5500 |
new narrow model. |
| |
A:
The 60 degree 90 and 115 by OMC are two fine engines....as are the
FastStrike |
| |
and Intruder V6's they're based on. |
| |
I'd strongly recommend a
jackplate....the setback will cure your venting problems |
| |
by itself but the ability to fine tune
the setup will help all the way around.... |
| |
Update....Thanks
for the info about the jackplate Todd, you are the only person |
| |
who has given me any type of answer
other than "I am not sure". Do you have a |
| |
specific brand of jackplate that you
recommend? If so, about what is the cost? |
| |
Are there different sizes of
jackplates, if so which do you suggest. |
| |
A: I like and run Rapid Jack
brand plates....they are showcased on BassBoat Central |
| |
and are in the $250 range....plus you
can have them colored to match your boat..... |
| |
it's a trick piece....I think you're
looking at a 4" plate personally....the important thing |
| |
here isn't setback as much as
adjustability....plus 4" will insure your steering and |
| |
other cables aren't too short. |

Q:
Todd, I think I have the correct stuff, what about prop? Need
better holeshot |
| 96
200 Merc |
and more top end....thanks for any
help. |
| |
A:
The 24" Trophy turns lots of r's and never gets anywhere
compared to the 25" |
| 24"
Trophy |
Trophy....anyhow....I recommend the
24" to guys who need rpms and are already |
| 6"
jackplate |
close on their speed....in your case,
the speed isn't there but the r's are. |
| 61
mph @ 5800 |
The 4 series Rangers have always dones
better with the Tempests and PS Yamahas. |
| 15#
psi |
If I were you I'd give a 25"
Tempest in A45, A47 or A48 a try.....steer clear of the |
| |
A46....rumors abound about a 24"
Tempest out now....I think the 25" Tempest at |
| |
5600 should do the trick for you. |

|
Q:
I would like to know if I raise motor 1" will my rpms raise to
proper rpms, also |
|
00 225 Merc EFI
|
what percent of slippage is normal. |
| |
A:
You simply have too much prop....you'll never get the
26" to 5800 without |
| 26"
Tempest Plus |
raising extensively and having
excessive slip. |
| 69.4
mph @ 5400 |
I have no clue now as to how high
your engine is....plus the V Series has no setback |
| |
in the hull like the VS and you list
no jackplate.....so you're kinda limited to raising |
| |
or lowering 1 hole at a time.
I don't know if raising will help or hurt without seeing |
| |
the boat run now. |
| |
My recommendation is add a
plate.....drop to a 25" Tempest.....adjust as necessary |
| |
starting at 3" under pad to
shaft. I use 6-8% slip considering all new modern props |
| |
have cup that isn't allowed for in
the pitch specs..... |

Q:
I am looking to get an aftermarket prop and I would like your
opinion on which |
| 01 200 Merc

one to get. It would be nice
to see 70 on the GPS and get a better holeshot, if |
| |
possible. Now the holeshot is
terrible, but the midrange is good and top speed is ok. |
| 25"
Trophy |
I have been looking at Turbos,
Powertechs and Mazco. Any info would be greatly |
| 6"

appreciated. |
| Propshaft
2.5" below |
A:
I understand what you're looking for.....but....the Merc
props are hard to beat.... |
| 65
mph @ 5800 |
and inexpensive. I recently
tried a 25 HP Mazco on a TR21 and wasn't really |
| 15#
psi |
impressed.....not so much as that I
thought it was better than a 25 Trophy. |
| |
This is what I'd do......try a 25
Tempest. If it works OK then try a 25 Yamaha PS.... |
| |
both can be found readily to try and
both can be had for less than 400 bucks. |

Q:
New boat on order, suggestions on prop, jackplate height and basic
setup? |
|
Comanche 520 |
|
| 01 200 Merc
EFI |
A:
The 520 is going to be a tad underpowered with the 200....I think a
23" Trophy |
| |
or maybe a 23" Tempest will be
needed....the new 200's are rated to 5800 rpms |
|
6" jackplate
|
now.....a 24" Trophy could
possibly be needed but the rpms need to be at least |
| |
5500. |
| |
I'd get a 6" plate and set the
engine at 3" under pad for starters....With the VS hull |
| |
design and the added plate you will
probably need to come up some....but start at |
| |
3". Nice rig!! |

Q:
Hello Todd, my boat had a '94 Mariner 200 which I just blew up, I
just had a |
| 95 200 Merc |
'95 Merc 200 put on and where should
I start at setting this rig up. I want the most |
| |
top end I can get (don't understand
below or above the pad), where should I start |
| 25"
Tempest |
and go from there, what should I
expect out of this rig? Any help is a big help. |
| 9"
jackplate |
Thanks....... |
| 2"
off transom |
A:
The 25" may be a tad large for the 491....the 23"
Tempest may be in order.... |
| |
wait and see tho.....if you can't
turn the 25" to 5500 min. it's time to swap. |
| |
Anyhow....find a straight
edge....like a yardstick or broom handle....lay it along the |
| |
very center of the pad till it
intersects with the lower unit of the motor. Measure |
| |
from the top of the straight edge
down to the centerline of the propshaft....this is |
| |
how much you are below the pad....in
your case for starters we are looking for |
| |
about 3". |
| |
I think low 60's will be about the
norm....maybe 64. Nice rig tho!! |

Q: Any
suggestions for more top end? Seems like too much boat is in

A:
Laser II has to go....add a Merc Trophy in say...22" pitch and
try it again. |

Q:
I have talked to several other Ranger 340 owners and they get a hell
of a lot |
| 89 150
Johnson |
more speed out of theirs than I
do...this boat is small...only 16'10"....feel it should go |
| |
a hell of a lot faster than it
is...no jackplate but does have the wedge plate for more |
|
22" Raker
|
tuck for some reason. Bought
it like that....I have to use a Stingray to get on plane |
|
3" off transom
|
fast...most of the weight is in the
back...tried a 22" Trophy and my #s really dropped |
|
57 mph @ 5800
|
so sent it back...just wondering if
you have a few ideas. Thanks..... |
|
17# psi
|
A:
I've done several 3's (370 and 360 series) and a 175 is good
for about 65 day |
| |
in and day out....a 150 is good for
low 60's. If the motor is strong and there's no |
| |
hull damage or lower unit damage the
boat should be capable of mid to low 60's |
| |
anyway. |
| |
To cut to the chase....your ability
to adjust is non existant.....a 24" Raker will cut you |
| |
to 5400 but add speed and a 23"
Renegade will add stern and bow lift and might or |
| |
might not beat the 22" Raker.
The jackplate is almost a necessity at this point.... |
| |
otherwise you have 2 prop changes to
try and there you are...I'd find a plate. |

Q:
This boat is on order and wondered what suggestions you have for
setup on the |
| 02 200 Merc
Optimax |
jackplate and prop. |
| |
|
|
25" Trophy
|
A:
The 25" Tempest is the right prop. The jackplate setting
was never measured on |
|
6" jackplate
|
my 518.....I'd set it at 2.5"
under the pad to center of shaft and work from there. |
| 99 Ranger
487VS |
Q:
Is there any way to improve performance of an Optimax engine?
I have taken |
| 99 200 Merc
Optimax |
two plugs out of my prop, should I
put one or both back in? Jackplate is a |
| |
Detwiler Hydroplate HYD600. My
holeshot and top end speed are O.K., but can |
|
25" Tempest Plus
|
I improve them without much expense?
Thanks for your time and any suggestions |
|
6" jackplate
|
you may offer...... |
|
68-69 @ 5400 +/-
|
A:
You have a pretty good setup now....it's the same components I'd
have under the |
|
15# psi
|
boat were it mine. There are
no simple tricks to the Opti....the only thing I'd |
| |
recommend is to try a Yamaha
ProSeries 25" on it.....the Yamaha prop was what |
| |
the Tempest was patterned after and
could give a tad more performance. |
| |
Just for giggles try a 25"
Trophy also......this will be hit or miss since the 4's like the |
| |
Tempests..... |
| 90 Ranger
690 |
Q:
At Lake Powell, UT (elev. 3700') my boat porpoises very badly at all
planing |
|
Fisherman |
speeds even when engine is trimmed
all the way in. Ranger says that a 4 blade |
| 90 175
Evinrude |
Renegade prop should trim the boat
out. Do you agree? |
| |
I also fish in CO and WY, (elev.
5000-6000') and the porpoising tendency is there |
|
20" Raker
|
but is not so pronounced. I am
afraid that the 21" min. available pitch of the |
|
48 mph @ 5700
|
Renegades might be too high.
Currently in CO and WY with my 20" Raker I'm |
| |
only getting 5200 rpm at WOT with
just me in the boat. Do you think a Raker |
| |
has a tendency to porpoise the
tournament Walley fiberglass boats? Thanks.... |
| |
A:
I think trying to reduce porpoise by prop swapping is a
hit or miss situation at |
| |
best....the reason it doesn't
porpoise as bad at higher elevation is due to the fact that |
| |
you're down on power and the hull in
turn isn't lifting to the point that the strakes are |
| |
in conflict. |
| |
Don't limit your choice of props to
OMC....Merc has a better selection and with the |
| |
Flo Torque hub kits for OMC, fitting
the Merc props isn't a problem....which brings |
| |
me to this point.....the Merc
Vengence prop is made for heavier hulls like the |
| |
Fish and Ski's that need lots of
lift and holeshot without affecting speed....the OMC |
| |
Viper does this also but isn't as
good a prop as the Merc version. |
| |
Your crossflow engine really doesn't
want to turn over 5500....so I'd be looking at |
| |
a 21" Merc Vengence....I'd also
be looking at redistributing some weight in the boat |
| |
to help the porpoise. The 690
isn't a hull prone to porpoise....so I'd say you have a |
| |
setup problem that can be cured. |

Q:
I am looking at a new boat and would like info like prop selection,
jackplate, |
| 00 200 Merc |
and any other valuable info that you
would throw in. This is going to be a big step |
| |
up from my 16' 40 hp boat with
tiller ;) |
| |
A:
You're probably going to need the 25" Tempest....I
haven't ran any R series |
| |
Rangers but it's base more on the
4's than the 5's......the 4's ran the Tempests and |
| |
the 5's the Trophys. |
| |
A jackplate is a necessity when it
comes to getting everything out of the boat that it |
| |
has to offer....6" would do
well. |
| 95 Ranger
461VS |
Q:
Todd, my boat runs strong with the 25" Tempest but I want to
improve holeshot |
| 95 175 Merc
EFI |
and willing to give up a mile or two
an hour to do so. I want to try a small hub |
| |
Trophy. What pitch would you
recommend? |
|
25" Tempest
|
A:
I used to have your exact boat......I ran 24, 25 Trophy's and
when all was said |
|
6" jackplate
|
and done the 25" Tempest was
the best. If you feel you have to go Trophy, here are |
| |
2 things.....the 24" will give
a decent holeshot but will spin a lot of rpms without a lot |
| |
of speed...the 25" will knock
some rpms off what the 25" Tempest spins but will |
| |
be faster than the 24" Trophy.
Give a 25" Yamaha prop a try and see if it doesn't |
| |
help holeshot and keep your speed
where you need to be. |
| |
To get straight to the
answer.....25" Trophy. |

Q:
I was wondering what 4 blade I should run to get the top mph I need
to run a |
| 98 225 Merc

4 blade because I fish Lake Erie and
big water and need a lot of bit but I also would |
| |
like some top end, so which prop
would you run? |

Q:
I know Ranger is not a speed boat, but I am looking for the best
setup to get as |
| 00 175
Johnson |
much speed as possible. Prop
is a 13.5 x 23" Renegade that has been modified to |
| |
a 25" pitch I was told.
Also would like to know your opinion on the best motor and |
|
25" Renegade
|
setup on a Triton TR21 for speed.
Thank you..... |
|
5" jackplate
|
A:
The 3 blades were my choice on my 4 series Rangers, my 5
series used the 4 |
|
69 mph @ 5400
|
blades. I'd get a 24"
Raker and give it a try. 5500 is what the book calls for on
the |
|
20# psi
|
small block OMC's, but they will
spin more than that with no adverse effects. |
| |
The fastest 21 setup is a 250 XB
Merc.....in 225's it's a 225 HO Johnson with a |
| |
225 Yamaha close behind. |
| 97 Ranger
R82 |
Q:
Should I be getting more speed than this? I also had a 6"
plate and speeds were |
| 98 150 Merc
Opti |
the same. Holeshot is fine.
Also have a 23" Trophy large hub getting the same |
| |
speeds turning 5300-5400 rpm.
The 3 blade has way too much bow lift. The |
|
23" Tempest
|
4 blade doesn't seem to have enough
unless I run the gas tank at 1/2 or less. I don't |
|
3" off transom
|
want to buy any more props or plates
unless I have to. I hope you can help. |
|
59-60 @ 5250
|
A:
As much as you probably don't want to hear it, 60 mph is about it
with the 2.5 L |
|
15-20# psi
|
Optimax. I'd say the 23"
Tempest is going to be the prop....a 23" Yamaha might do |
| |
a tad better but probably wouldn't
be worth the aggravation. I have experience with |
| |
the early 2.5 Opti's and it has all
been bad. The engine just isn't very strong. |

461VS |
Q: Todd,
I'm new to the game of dialing in my bass boat. I am looking
for |
| 97 150 Merc
EFI |
recommended jackplates, engine mods,
(ie. tuners, reeds) and what props to make |
| |
my 461VS achieve top speed
performance. I have an outboard mechanic friend |
| 23
Trophy |
who brought his Quicksilver
Diagnostics computer on board, and hooked directly |
| 59.0
mph @ 5950 |
into the ECU to get the exact rpms
at WOT. Here's what we found with several |
| 18-20#
psi |
props: The Trophy 23- rpms 5950, mph
-59.0. Trophy 25, rpms5400, |
| |
mph - 61.8, Tempest 23, rpms
5750, mph 61.9, Tempest 25, rpms 5350, mph |
| |
62.5. Surprisingly, each of
these props had little effect on my holeshot time to get |
| |
up on plane (about 5 seconds). Now,
where do I go from here? I really appreciate |
| |
your help. |
| |
A:
That's a pretty good set of test numbers....it also proves what I
preach about |
| |
the 4 series Ranger....they like the
3 blades. Adding a 6" plate will alow the 25 to |
| |
spin up to 5500 and be good for
64-65 mph....with no other mods. |
| |
Going to a new 24 Tempest would get
you to 63 mph at 5550. |
| |
The plate will give the most bang
for the buck....there are tons of mods that make |
|
|
the 150 come to life....the tuner
being the most prolific....it's also kinda costly and |
| |
can cost some bottom end punch for
holeshot. A 461 with a non-plated 175 EFI |
| |
and a 25 Tempest is good for 66-68
mph....a 150 is generally going to do what |
| |
you're getting now....I have one
that has a 200 carb on it and it does 66 with 2 |
| |
BIG men on board with a 25
Tempest...up from 60 with a plate adjustment and |
| |
chunking the 24 Trophy. |
| |
A 461 is a great boat....but not a
speedster...if it were me, I'd plate if at 6", add a |
| |
25 A45 Tempest and get it to
65....if I needed more I'd pull the bucket and add |
| |
the tuner....and possibly an SVS
even though it didn't work well on my |
| |
518/200 EFI....but it didn't have
the tuner. |
