Froze up 115 still soaking

[GatorMike]

I posted a few days ago about my 115 Johnson that had sat for 9 months and was frozen up. I soaked filled the two cylinders that were out past the exhaust ports with PB Blaster and poured some more PB Blaster in the other 2 cylinders and let it soak a couple of days. It was still froze up so I soaked it again in Marvel Mystery Oil for 3 more days and still couldn't break it free. My neighbor who is an auto mechanic and a pretty good all around handyman suggested I remove the heads and spray the cylinders good with corrosionx. I did this on the left side which I have reasons to believe is the bad side for 2 more days. I haven't got the heads off the right side yet due to a stuck bolt and a lack of time to work on it but I have just continued to soak that side as I have been doing.



I have put about 140 lbs of torque on the flywheel nut and she won't budge a bit. I have tapped a little on the pistons with a hammer and a block of wood but don't want to over do it. I'm going to post a link to my previous thread which is a little more detailed in case more information is useful. Anyway it looks like I'm going to be tearing this motor down when I get the time. Does anybody have any other suggestions I might try to break it free in the meantime? Oh one other question I had been meaning to ask, with stuck rings would there be any play at all in the flywheel? Mine is solid, no play at all.

I think "stuck rings" might be wishful thinking, I think you have a major drama on your hands, one that will require some proper care and rebuilding, sounds more like a stuck bearing if there is no play in the crank at all.

try applying your 140 ft lbs and giving your block of wood a good rap multiple times while the 140# is still applied. one it is loose that will let it free up but sounds like a rebuild is in your future anyway

Stuck after only 9 months? Very odd. I would say that "seized" is the proper term. How did it get stuck?

In April we took it to Marco Island for a week vacation and she ran fine all week. When I got home I flushed it out and did a quick compression check which was good. The only reason I did a compression check was because I happened to have the guage in the tool box I took to Marco. I wasn't expecting a problem. Anyway I noticed at that time a little rust on the lower left spark plug but didn't think much of it. I didn't fog the motor when I put it away because I didn't expect to let it sit so long.

Anyway the other day I went out to start it and it was froze up.

My friend had a 115hp evinrude, and hoodlum neighbor kids.

They figured out how to start it, and would go over to his place, start it up, and play with the throttle/shift lever a lot.

...could this of happened?

Uh oh, sounds like water intrusion from possibly a blown head gasket

I would try to "pickle" the engine. If you don't know what that is, the short version is filling all open space (including the cooling system and crank case) in the engine with Diesel Fuel for a few days. If the engines is not sealed this may mean submerging it in the Diesel.

There is more to it but you'd have to read up on it, which I am sure you could find by googling "Pickle Engine" or "Pickling Engine".

This procedure is used by salvage operations.

Re: Froze up 115 still soaking

And my submerging, I wasn't suggesting the whole outboard, just the engine. Although the seizure could be in something other that the engine. You may want to pull the lower unit and see if it is still seized. If not still seized then maybe pickle the lower unit.

Re: Froze up 115 still soaking

If the lower unit is the culprit, you will need to redo all the seals since it most likely was due to rust or other water damage and water shouldn't be in thier. I didn't see a mention of replacing the lower unit oil when you winterized it/stored it.

Good luck!!
