14ft fiberglass with 4 guys totaling 800lbs. boat,4 guys and an inch or 2 of water under the sub floor. too much for a 50 force to handle?<br />It over heated and died on the lake, fortunitely no damage done. the impeller looks like new, water flows freely with earmuffs' on. Hard to tell what the waters doing with it in the lake as the water discharges through the bottom accept for a little spray out the small holes out of the water.
