I’d take the drain plug out of the lower unit and see if there is fluid in it, grease, whatever you want to call it, rather than rust powder. Better yet, take the lower unit right off and see if it spins over better. Old Mercurys are notorious for water damage and failure of the lower unit, especially after having sat a long time.

Long live American manufacturing!
