Fits several year models. I think this is off a 1981 50HP Merc. I'm not an outboard mechanic but I can tell it has neutral, forward, and reverse gears. Shaft is 22" long with 11 splines. Seals look good. As far as I can tell all it needs is a new water pump and a trim tab. Sold as-is with a bill of sale. local pickup only. Comes with 2 props.
