I run a Ranger 364v 18' boat with a Rude 150 25" 13.25 dia Shooter 4 blade. I get about 62mph out of her and the holeshot sucks any help would be great?

Good Fishing,

Sounds like you re overpitched for that setup.  Do you have a jackplate or anything else on that motor?

What kind of RPM's are you getting?  

You should be getting 5500+ RPMs at the top end.  You should try a lower pitch prop, maybe a 21."

 

That's a lot of prop for a 150 on that boat. Find someone that has a 22" raker that you borrow to try. I believe you will be much happier with hole shot and top speed. If you're running a 6" - 8" jackplate, set the raker at 3 1/2" below the pad to try it. As mentioned, you want 5,500 rpm with your normal load, at WOT, maybe even 5,600 - 5,700 this time of the year. Your motor is going to loose a couple of hundred rpm when the weather and water gets warmer.

Have you done a compression check? Make sure you're running equal compression on all cylinders, approx 80 psi plus or minus 5%. I'm guessing that is the 90 degree X-flow 150 (pre 92).

I'm running about 5500 rpm. No jackplate though. I was thinking about a 24 or 25 pitch renegade. Top end is fine but haven't done a compression check.

Those motors hate renegade props. They don't let the motor get up where it needs to make torque. Never tried the shooter so can't comment on it but if they respond the same to the shooter that they do with a gade, that may be some of your problem. You will probably even have worse hole shot with the gade.

Check the compression, or if you have the capability, do a leakdown test. Loss of compression can make one a real dog trying to get on plane. Since compression has little affect on hp, it can still make good speed once up and going, but compression has a huge affect on torque so hole shot suffers bunches with much of a drop. Especially since they had already droped the compression of those motor so much to burn low octane gas.

Might want to make sure the timing is at least 26 degrees also, book calls for 28 but with this junk we have for gas, if you don't keep fresh or run 89 octane gas, 28 can get you in trouble.  Easiest way to check and see if your close, disconnect (take the plastic pin out) the rod going from the throttle lever to the cam, this lets you advance the timing fully without opening the carbs so the motor only revs to about 2,000 rpm.   While doing all this, might as well make sure the pointer is zero'd for TDC.  Make sure the carbs are fully opening also.

Thanks very much for the info. Guess i'll check comp. I've heard nothing but bad about the shooter prop.

Good Fishing,

damm it boy.... try this  change the cup to a full and add blow out holes if that is done you need to drop the pitch... check what and why thats not going to help you out of the hole. Either you have top end or hole shot then you have the middle road. you can not have both at the same time on a prop.... and if you want some real good answers write to the byuboyz at byuboyz.com there the OB guys who race here in Texas or you can call Greg Moss at Moss Marine in Kemha Tx i think i spelled that right. Just my .02 cents from the mud squriter  ;D ;D
