Perfect Pass not holding, prop bent?

[do420jc]

I have a 21v with a 4 blade prop 14x18 and to boot 2 of the 4 paddles are bent. I know it is the wrong prop for the boat and have ordered an Acme 525 3 blade. My question is because of wrong prop and being bent will that cause the PP not to hold well. Or could it possibly be my perfect pass. I rec. had the servo motor replaced so I don't believe its the PP. Any help would be greatly appreciated.

If the PP sets & Tries to hold, I would replace the prop first, and test the PP again.

Are the engine RPM's increasing while the boat speed stays steady or slows (W/ PP on)? A bent prop could cause enough cavatation that the prop is just 'pushin air'

Hate ya bent one, good luck.

PP holds 80-90% of the time. I do notice the rpm's moving around when PP is on, not alot but does move. It seems to drop when we are going around a corner or turning while towing a rider.

It will always move just a little bit. The key is not having it move more than .1 or .2 MPH.

There's always going to be an issue in turns because of the location of the paddle wheel...not much you can do about that.

PP and Props

It could certainly be the prop. This June I had a Michigan Wheel on my 22i as a temporary fix. It was pitched wrong and as a result I experienced a lot of cavitation out of the hole and on turns. Perfect pass went crazy trying to keep up (I had it set on MPH in wakeboard mode/not RPMs). Changing the prop to an ACME 515 did the trick. Now it tracks within .3 MPH of the setting. I would certainly try the correct prop before messing with perfect pass.
