Here i go again. Recently I bought back my 23 after a 1 year absence from sailing*(i bought a donzi-not the same). He replaced my 15 hp 2 stroke with a new tohatsu 15 4 stroke. Around here you need a lot of juice to move against the tide to dock and get to and fro. Is there a weight limit on this boat for motors? I sail out of St. Simons Island Ga,
