I have a 10 ft sea nymph v hull. I was wondering if a 6 hp two stroke would be to much for it. the coast guard saftey card says 5 hp max. I know a 5 and a 6 weigh the same. My thought was when getting into rougher waters out here in sd bay the 6 would jump up and down on the transom ripping and tearing it apart. I would like some input on it please.
