Default Re: Need ideas to stop porpoising?

Based much on what has been well documented on this site, I'm gonna guess that you'll pick up some of those rpm by raising the motor. Start there. 1 hole at a time or whatever to takes to get the anti-cavitation plate 1 to 1-1/2" above the bottom of the hull with the a-c plate parallel to the bottom of the hull. Seems to be the magic number...

I don't see a 200 optimax having trouble turning that prop but as it's said some props are easier to turn than others. What is your prop style/model? Based on what's out there for that motor the your current pitch is about as low as you can go, I think any thing lower will will likely be detrimental to your overall performance.

Tend to the motor height first. You may find yourself pleasantly surprised. Keep in mind your full windshield and top and radar add considerable drag compared to Gary's walk-around windshield. I think if you pick up the rpm and squeeze another couple mph you're smiling. Good luck! Post your results, like to here results.
