90 HydraSports	Q: I'm looking to purchase a jackplate for this boat. It doesn't have one installed
DV 180 SX	at this time. I would like your recommendation on the make/model/offset/size of
90 120 Johnson	jackplate for this boat/engine combination. Thank you.......
20" Raker	A: I'd recommend a 6" Rapid Jack for the HydraSport.....this is a boat that
	comes to life with more setback.
97 HydraSports	Q: I feel as though my holeshot is OK, but not anything spectacular. Skeeter's
97 225 Evinrude	with 150's take my by ~50-70 yards. My time 0-30 mph is 7.5 seconds. I can
	catch those Skeeters but well after we both get into the 60's. The handling is great!
25" Shooter	Is this a good setup? Would changing to a 3 blade prop w/higher pitch improve
6" jackplate	my WOT speed? What about overall performance? (There is always a downside).
5 7/8" off transom	What is your overall impression. Are there any easy ways to squeek out a few mph?
66.7 mph @ 5900	A: It's not uncommon for 150's to have a better holeshot...the thing that makes
22# psi	them 150's adds to low end torque....mainly restricted port timing and exhaust....
	but the restrictions that add torque cost them on top....the big block OMC's have
	never been holeshot screamers....nor have Merc or Yams.....but I'd trade seconds
	on 0-30 for mph on top.
	I'd advise chucking the Shooter....try a 25 Renegade....but also try the Rakers....
	prop swapping is the easiest way to gain or lose performance...and trying is free....
	5900 with a 25 Renegade will put you to 70 mph....about where the 205 runs with
	a 225....the 205 is an excellent boat.
84 HydraSports	Q: What do you feel would be best setup for this boat. Also have 23" Yamaha
VL-475	ProSeries prop I sometimes run in summer about same numbers.
84 150 Merc
	A: The 25 might be a tad large for the 150....the 475 is a pretty quick hull though
25" Tempest	and should turn it ok....the r's for speed show excessive slip...probably why the 23
6" jackplate	runs about the same.
5" off transom	I think you might come down a little....that should drop the r's and up the speed....
61 mph @ 5800	the propshaft will be about 2.5" under pad when reset.....go up or down as needed.
23# psi

90 HydraSports	Q: Exhaust relieved, drilled cooling passages, Boyesen reeds, WH-28 carbs with
X-270	0.080 mains, 0.046 idle jets, round tuner, exhaust line pulled, driveshaft housing
2.4 200 hp Mariner	drilled at bottom, Bob's LWP, electric fuel pump @ 6.5 psi. Turns same rpm
	with both props. Little slow coming up, but when tach hits 2500 it's gone.
27" Yamaha	Speedo only goes up to 45 mph. I know it's faster than that. Any ideas or tips,
23" Laser II	adjustments, you would recommend would be appreciated. I only live in
6" jackplate	Hermitage (TN)!
5" off transom	A: MORE SETBACK!.....a chopper style propeller, what's your compression?
6600 rpm	6600 with .080's is kinda lean....my old Mod VP with W24's ran 92's and would
22# psi	go lean in spring requiring 96's.
	It's gonna be slow on holeshot.....all the exhaust mod's and tuner will kill the bottom
	and give it up on top...hence the free'er spinning chopper style prop......James at
	Performance Prop will let you try as many as you want....
	Jimmy Loper had (has) the same exact boat without the custom work....we swapped
	a 29 SRX for a 28 Turbo and it peeled all the paint off the lower unit....that usually
	takes place at about 80 mph.....you've got a good start on mid 80's.
84 HydraSports	Q: I have tried different heights with my jackplate. I am looking for a good SS prop,
VL-270	but don't know what pitch or brand to get. My factory 19" prop has been pitched
78 140 Johnson	up to a 21" and also had more cup added to it. My problem is I only get 50 mph
	out of my boat @ 6000 rpm. I would really like to get into the mid 60's with less
21" Aluminum	rpm. My prop is in great shape with no slippage. I don't want to spend a crapload
6" jackplate	of money on a prop I won't be happy with. It was suggested to me that I buy a
3.5" off the transom	22" Raker, but I don't see how this will get me what I want with just 1" pitch higher
50 mph @ 6000	than I'm running right now. Can you suggest a good new or used pro for me.
12# psi	My engine has also been completely rebuilt, and bored .064 over with Weisco
	pistons. I would appreciate any help you could give me. Thank you..........
	A: First of all......you can't repitch a prop...period!! It can be cupped to add the
	equivalent of pitch.....about 1" max. The pitch is achieved when the blades are
	mated to the hub....unless the blades have been removed and rewelded completely
	it hasn't changed pitch.
	Your prop can't beging to be compared to a Raker in terms of rpms...totally
	different animal. As far as no slip goes....you have a ton of inefficiency at 50 mph
	at 6K.....that translates to 59 mph with a 21" with no slip on a 2:1 gear ratio.
	Don't try to find a prop based on what you're doing now....I'm going to be point
	blank, I don't wish to hurt your feelings....your setup is crap and it's all due to high
	slippage....get an efficient prop....maybe lower the engine and start over....fire your
	prop guy too.
	I wouldn't commit to a prop till I tried it first.......
79 HydraSports	Q: Todd, as related to you in an earlier question, I have a very severe porpoising
178 VEE	problem at low speeds, less than 35-40. Over 40 boat is a dream once it gets on
95 150 Evinrude	the pad. What is your recommendation? I have thought about a StingRay since I
Intruder	believe this would be out of the water when I am up on the pad. The 115 hp that
	was on the boat would never get it up on the pad and I had a Sting Ray on it and
24" Raker	the boat was very nice at slow speeds and rough water.
6" jackplate	A: I've never been a big fan of whale tails. What I'd do is borrow a 23" Renegade
62 mph @ 5200	or adjust my engine with the 24" where the hull will transition past the point that the
22# psi	strakes are in conflict....almost every boat I've had will porpoise some at a given
	speed.....not as bad as what you seem to be going thru tho.
89 HydraSports	Q: Last year I asked you about the setup on my boat. The setup I have now is
176 DC	what you suggested. The problem is my rpms, they're too low and could cause
89 150 Johnson GT	problems with the motor. My rpms should be at 5600 but am running 5200 on the
	norm. I have run as high as 5400 and as low as 5000 depending on the air and
24" Raker	water temp. I was told that running a 23" Renegade 4 blade with added cup will get
6" jackplate	the rpms and also get me the speed close to what I'm running now. I tried the 23" -
5" off transom	3 blade Renegade once but did not run out as good. Am I going in the right direction
57 mph @ 5200	or if not can you direct me that way.. Thank you........
30# psi	A: A 23" Renegade will turn the same r's basically as the 24" Raker....adding cup
	to it will kill the r's .....not up them.
	They don't make a 23" Renegade 3 blade...just a 4 blade, and a 22" and 24" Raker.
	From looking at your results I'd recommend a 22" Raker....that should get you to
	5600.
96 HydraSports	Q: Holeshot terrible; I've raised to two and one half below the pad and it seemed
96 175 Merc EFI	worse so I lowered back down. Seems better, I'm wondering whether to go down
	more or way up; I'm not a speed freak, just want a combo to get me out of the hole.
25" Tempest A40	Is this a boat that likes the motor really low? Any help would be appreciated.
6" jackplate	A: Well....if the engine is bogging while coming on plane....raising is usually
4" off transom	required......if it vents excessively then lowering is what's needed.
72 mph @ 6000	If it is bogging you could have your exhaust holes enlarged on the A40...just need
15# psi	to be sure to not over do it.
	For quick comparison, raise it then lower it a full 1/2" each way to see what happens.
