just bought a very little used 93 challenger radical one pro 198 with a 150 mariner on it. brand new 25p merc prop. how can I get rid of the porpoising? I trim up for speed and it porpoises. trim down and it stops but I lose speed. can't like losing speed. maybe lift motor and keep an eye on water pressure? it has a 10" jack plate also.

Probably need to lower the motor to keep it from slipping and falling down.
