powerboat

I have a 1989 28'Sleek approx 5000lbs wet. I have just rebuilt motor approx 500HP. I have tried a 26p bravo 1 and a 24p hydromotive. The boat seems to porpoise when I trim it all the way up to get top speed. Approx 63MPH 113 degree day. I had a 3 blade 21p mirage prior and don't remember it porpoising as bad before. Second since the rebuild and repaint I have notice the boat rides crooked to the left side and have to tab it straight. I am not sure if there is a weight dist. problem and if there is how much would it take.The props are all right hand rot.
Any thoughts would be most helpful.

If these are Bravo drives why are you not counter rotating them? also the Bravo 1 props are transom lift props. If you didn't raise your x dimension and you didn't have a problem with blowing out on take off ---- go back to the 3 blade mirage + prop it will give you more bow lift than the older standard mirage.

powerboat,

I believe all 28 sleeks coming out of the factory today have left hand rotating 3 blade props. You might want to call sleek craft and disscuss this problem with them.

I hope this helps,

Thanks that helped out a lot Jack said they are running 24p bravo 1 left hand rotating to level the boat out.
