He suggested the Merc Big Foot as it had a larger cavitation plate. I am not into hydro-dynamics, so is this just a sales pitch? Any experiences here anyone? I am buying something at the boat show in Jackson, Tn. this next weekend. No doubt about that. Just need inputs here.
Is your motor mounted properly on the boat? With the motor vertical, look at the cavitation plate on it. It should be even with or just slightly higher (1") than the bottom of the keel.
