This is an early model Mercruiser outdrive. I bought a boat for it's other parts, the engine wouldn't turn over, I removed this from the boat, then the engine turned over. This is seized and the prop shaft has come out of the housing. Im selling as a parts piece only , as the housing and possibly the upper half of the drive may still be good. It is marked as a 120/140hp. It was hooked to a 150hp in-line 6 (see my other listing for the engine). This is the earlier outdrive that had both hydraulic rams and shock absorbers.
