Hi - i have a jack plate that will raise the engine 5"- its a TH Marine unit, only 3 years old. Just removed due to engine change! its a manual adjustment. pm me if interested!
There are both jacking and missing plates available, both will add stress on the transom in one way or another so be sure your boat can handle it. Ive just put these plates on my 4.3 centre console to accomodate a 25in motor.
