22ft bay boat issues

When you take off from a stop does your bow raise up pretty high then take 10-15 seconds to level off? If this is the case your motor could be too low

Meaux is right. Motor too low can cause this issue. Have someone drive while your on plan and look how the motor is riding in the water. Is the cavitation plate completely submerged? If so your motor is too low. Measuring cavitation plate height relative to keel is just a rule of thumb. You need to see how the motor is riding when on plane.

Also your prop could be adding to the problem. Some types of props are "bow lifting". This could be the problem or add to the problem.

Yup my 21' nautic star was having some issues with porpoising. I had installed a mercury rev4 prop not knowing it was more of a bow lifter. Switched over to the turbo and it acts like a different boat.
