1986 50 HP Mercury, I believe it is a short shaft. Motor has tilt and trim, and comes with all controls. Has had the Carbs rebuilt, new water pump impeller, and a new fuel pump. Motor was not running when we took it off the boat, needs the carbs adjusted. Has great compression and spark. I just upgraded to a bigger motor so did not bother fiddling with it. Asking 700.00 for the motor and would prefer local pick-up near Dayton, Ohio. PM me with any questions and inquiries.
