Ok, I just bought my first boat so forgive me for my ignorance. I have an Alumacraft MV 1448 and I purchased a Tohatsu 20HP tiller online which I have yet to receive. My question is do I need plywood between the transom and the motor clamp when I mount the motor? I looked at several new boats with motors before I made my purchase and noticed they had plywood sandwiched between the transom and motor. I assume this is to offer support and distribute the pressure on the transom from the clamps.
