GP1300 unhooking at WOT
At WOT the ski is bouncing and comes unhooked like crazy. I've lost too many races because of it. My sponsons are stepped and I'm running a T&B 14/20 Solas DF with serval other bolt on modifications. I've heard that I'm bouncing too much because the impeller is too steep. Does anyone have any advice on this? Thanks

shim your ride plate had the same problem....and use your trim.

Not sure how a prop being too steep can cause you to come unhooked at speed. Better use of the trim might help.

Should I shim the trim tabs down as well?

How big is the water that you are raceing in.... smooth, 1 foot chop, 3 foot chop?. How long is the race? How long are the straight line runs? Is it closed course?
You are right in that your boat is not making power while it is in the air, so the trick is to set it up to where it stays hooked up without creating so much drag that overall speed is reduced. In other words, you have to set your boat up for your racing conditions using only modifications that suit your needs.
Most of the speed tricks that you read about will help in smooth water, but in racing conditions with your buddies or even in formal racing, many of these so called tricks will not work and may actually work against you.
So what are your racing conditions?
You may be surprised if you do a search on Shredmaster ride plates, and 3 degree nozzles on GPR's, and thrust nozzle adjustments. This is the beauty behind the GPR. You can set it up to do so many things and do them well. You just cannot do them all at the same time.

I put two washers on each side in the back of the ride plate like 1mm washers......and you just play with the trim up or down

Hi Black&Siver, have not heard from you lately .... My 08 1300, stays hooked up pretty good but not to choppy hear ... except in CC races where it gets churned a fair bit. I was wondering do you have any sort of hole shot ? I know our top-ends are about the same. I just think my ski is still a pig out of the hole. Any ideas ?
