I hadn't thought of that, of course! You might actually be right, the outdrive might be frozen, not the engine.

I've already removed the tilt quadrant and lowered the drive down. And yes you assumed correctly, the boat is on a trailer. I will separate the drive and remove the shaft and bearing from the transom.

When you say the bearing might be frozen, I assume you are referring to the bearing at the carrier around the ball gear, that you described in your post. Am I correct?

BTW, I've ordered the Seloc manual and should receive it Wednesday.

Once again, thanks for all the help so far.

This is the the catch-22 i don't want to be right.

I don't want your drive to be frozen, but i can't see or touch it.

I don't want your motor to be frozen.

This is a ole girl and everything has to be inspected anyway.

Water pump has to be rebuilt in the drive. Gears inspected.

I wish you would post pictures of the drive and the motor.

The ball gears how they look.

The engine mounted water pump is it frozen?

Take off the belt see if you can turn it bye hand.

Take off the alternator belt can you spin that?

Leave off the belts for now.

Take off the valve covers shoot everything with pb blaster.

There is alot you can do now before the manual comes.

Drain the gas tank.

Check the vent it clear.

Check the anti-siphon valve.

This is actually the second time i told someone to pull there motor.

Pull the motor nothing can be trusted, coupler splines every brass plug inspected.

Risers manifolds all need to be inspected.

Hoses.

Good news and Bad News.

1st the Good News: The motor is not frozen. It cranked over easily!!

Bad News: Something in the outdrive is frozen.

As per chiefalen's recommendations, I seperated the outdrive from the motor and cranked it over, and it spun easily. Nest step there is to replace all fluids, filters, ignition parts, etc. and actually start the engine and tune it up.

Next is the frozen outdrive. It is an electric shift by the way, as I think it makes a difference. It doesn't have a shift CABLE, what it actually has is an electric wire that goes through the transom to the outdrive.

I tried spinning the outdrive's ball gear by hand after separating it from the engine, and it wouldn't budge. If someone were to take an educated guess before starting to tear into the outdrive, what do you think is the problem? What has caused the outdrive to lockup this way?

If you have the low profile electric shift, convert it to the later mechanical shift. You should be able to find one for near the same price as rebuilding the electric shift unit, assuming it is froze up.

You would need to get the shifter and cables, the shift converter and the drive with appropriate shift cable. You'd be good to go. It's pretty much a plug and play conversion with a few tips and pointers.

greetings and welcome. I might have missed something in a post and don't really know much about OMCs, but you mentioned getting the engine running now that you've removed the drive. How do you get water to it to do this?
Not second guessing, just curious.

WizeOne and chiefalen: The boat is in Southern California.

Thunderroad: At one point in the thread, it was thought that the engine was frozen. I was just attempting to get the engine to turn-over, not fully start and run. When I seperated the outdrive, the engine cranked over. I did not attempt to start it and run it continuously. As a matter of fact the fuel line is disconnected from the fuel pump.

I was just going through some diagnostics to determine what needs repair on this setup, and so far it looks like the outdrive needs work. I would not run the engine without any water!!

You could if you want run water to the long hose that connects to the t-stat.

Just a fitting or 2 to reduce to a garden hose.

Just to run it 5-10 minutes would give enough water.

Don't go over 1200-1500 rpm ever on muffs.
