I have a 1983 7.5 hp Mercury outboard that has not been run in several years. The lower unit was not attached due to attempted/aborted repairs to the water pump. Today, the flywheel/pull rope will not budge. I made sure that everything is in neutral when trying to pull start it. I put it in gear without spark plugs in place and tried to turn the prop with no movement on the flywheel. I removed the lower unit and tried to pull with no success. It is stuck/frozen. I pulled the exhaust housing and the visible portion of the pistons look clean. The piston faces look fairly clean. Is there a safety lock that may be engaged and overlooked. Is it possible that the crank case/driveshaft is corroded to this point, if so should I sell it for parts or soak it some how in a solvent? The motor was kept in my shed out of the weather during this time and the motor looks nearly pristine otherwise. Thanks in advance for any help on this.
