I have a 90 hp Nissan and the cavitation plate is about 1-1/4" above the bottom of the boat. It sucks air real bad when turning, should I lower the engine down on the next hole or should I try one of those fins that mount to the cavitation plate?<br /> It's fine when taking off and running on straight aways but the turns the boat slows and the engine revs up. Any suggetions?
