I bought a pontoon boat that has a Mercury Classic 50 on it and the previous owner put a whale tail on the motor . Will that help or harm the performance of the boat ?
These two are spot on. I ran a dole fin on my previous boat (17 ft sea ray 3.0). It did help with planing until it cracked my cav plate…
on a 50 hp toon any improvement it wishful thinking. Try it with and without, if it does any thing positive would suspect that it is covering a motor height issue or other setup problem
