I took my boat out today and had a problem. The boat ran fine and I stopped for a few minutes. I turned it on again and heard a grinding sound.

I slow down and turn it off. It would not crank over and not sure if the pump bearings went out and would cause the motor to seize. The best way to tell if the problem is in the top or the bottom is to seperate them.

I had a guy bring his motor in and it was frozen tightHe said he filled the cylinders with oil and let it sit for a week or two and it was still frozen. I dropped the lower unit and found a bushing on the driveshaft that bound the motor up. If you didnt winterize it and it was exposed to freezing temps.

You are probably going to have some motor work to do. Sounds like since you didnt fog your engine before winter the crank bearings may be rusted up or the pistons stuck in the cylinder. The way to tell if it is locked up is what you tried.

If it wont turn over it is locked up. Check the voltage on the starter at the terminal closest to the starter motor. If no voltage when cranking the solenoid is bad if voltage is good and the starter doesnt clunk the starter is bad.

If the starter clunks then the engine is locked up. Remove the spark plugs try cranking the engine. If it moves turn up the pressure on the impact wrench and let it spin freely.

If the motor refuses to turn add more penetrating oil and periodically use the impact wrench to turn the crankshaft nut. It should eventually free up. Remove the rags and let the excess penetrating oil escape from the cylinder while you spin the motor.

The engine has run out of oil. The oil is not circulating properly. The friction between the metal parts running against each other is creating a tremendous amount of heat causing the engine to seize.

1 Patience and 2 penetrating oil. Usually there is a nut or bolt on the crank end that can be used to try and turn the engine but the danger of breaking it off means a safer alternative is to use a lever on the ring gear through the starter motor aperture. The engine will need.

If the engine does not turn it is most probably seized. Remove the spark plugs and try to turn the engine. If the crankshaft is rotating properly pour a little penetrating oil into the cylinders through the spark plug hole.

If the oil goes in successfully your engine might not have seized. The problem with a seized engine presumably been siezed for some time is that the mechanical advantage of the crankshaft moving the pistons depends on the position of the piston. So when a piston is misd stroke it moves a lot with every degree of crank turn while when the piston is at top it moves very little for crank turn.

For a bad starter common engine seized symptoms include infrequent oil changes and running the engine out of oil. It could also be a broken engine oil pump or a sudden engine failure. For a hydrolocked engine youll know its cause when it happens.

Engines rarely seize but when they do it is almost always due to a long period of nonoperation. When an engine seizes one or more pistons have literally become stuck against the cylinders wall.
