    Default should I move the motor back?

    My motor seems to be way farther forward then most the boats I see. From what I have been told is my pump is the old style that uses a longer shaft than whats out there now. the only way I could see moving the motor back would be to get rid of the H-bar and run a single Ujoint. Any ideas? I'm thinking it might help to get rid of the porpoise I have.

    Single U joint will likely result in a drive line failure.

    And moving the motor back will not reduce porpoise, it will make it worse. A Place diverter will solve your porpoise problem.

    Actually putting the rideplate on gave me the porpoise. Diverted only helps all the way down. Any other slot it porpoises.

    is your boat faster when it's got the porpois going on? The ride plate may need to be lowered, to settle the porpois. Moving the engine back will really un-settle the boat, inducing porpois.

    The bottom is straight. The shoe is level with the keel. Shunning the plate had no effect all last summer

    It has two outer strakes that go to the transom on each side of the intake and a inside strake that terminates at the intake inlet, the bottom of the boat is 7/8" thick in some places and its all straight
