So your replacing an 80HP with a 50 HP? Not that the 50 is not a good motor, and a nice find, but isn't that going the wrong direction performance wise?
its on a 15' Larson (62 playboy) which is basically a flat bottom boat, at least at the stern.
it has no rating plate but originally came with a 40 i think.
it handles really weird withe the 80 hp long shaft merc on it, tried a jack plate to get it up higher but made it handle worse, i think its too much weight. and boat has a short transom. top of all that merc don't start good when its hot.
so i decided since i stumbled across a great deal on a short shaft which seem to be really hard to find i would just call it. it lives on a small lake so really don't need to be over powered anyways.
