1995 Murcury Force OB Won't Start

[Papa Don]

I just bought 2 120 HP motors. One starts one<br /> will not. They sat for 2 years. (The one that<br /> won't start) The starter enters the flywheel<br /> but will not turn over the motor,some times it <br /> will but very slowly. It will kill the battery<br /> if i keep tring. It turns over hard with a <br /> wrench. The person i bought them from stoped <br /> running also. He got 3 to 5 for theft.<br /> Can anyone out there help ?<br /><br /> Thanks in advance.<br /> Papa Don

So, the same battery can crank one engine fine but not the other...<br /><br />Sounds like the other is partially seized. Spray some penetrating oil down the cylinders and let em' soak, see if this helps.

Pull the spark plugs and put a couple of spoonfulls of outboard oil in the holes. Let it sit overnight and see it that improves the turnover. Corrosion may have set in on the cylinder walls.
