To Jack Plate: Done, Need Help!

[Jimmy Easterling]

For those who were not envolved in the discussion before the JP, Nitro Z6 w/115 Opti, prev hole shot empty about 4-5 seconds and top end 47 mph. I had a 5 1/2 inch manual JP installed and put in the water today. Same distance, which is only a few hundred yards since our lake is only that long, mph is about the same and the hole shot is a little slower. Water pressure is holding at the same as it was prior to JP and when the motor is adjusted up high I get a little chine. I moved it down a little and it goes away. Here is the kicker, I have to throttle back at any position because the rpm's are too high. I am sure that is a good problem to have since I am guessing I need to change to pitch on the prop. Right now I have a Laser II 20 P. Any suggestions? The dealer has a Laser II 24 P he will loan me, is that too much of a jump?

 

[Bruce Yeaton]

Ya, way to much jump I think. A 21 or 22 pitch should be fine, but depends on what rpms you are getting with the 20P. A 22P will drop 400 rpms.

 

[Jimmy Easterling]

I get an overrev beep and code at 5900. I have to back off to keep it below that. Right now it will go easy above 6000 rpm.

 

[TOMMY RICH]

Agree a 21 would be a good start.

Theres really only one way to find out if its too big or not. If the dealer will loan it to you to test with its worth a shot, you really have nothing to loose in that situation.

 

[Randy Walls]

I have a TV-18 with the 115 Opti and I have a 21p three blade. Runs just under the limiter so with the glass that is naturally faster a 22p sounds about right. See if the marina you bought if from will loan a couple out of each size to see.



Goo dluck with it.
