110HP Evinrude Mess

[coachbrent]

I bought a boat with an Evinrude 110hp that was supposed to have been rebuilt 2 years ago. I doubt it because one of the spark plugs was broken off. The boat was then stored and not run. I took the heads off without too much trouble, only broke 4 bolts. It looks as if the motor cover was not on the motor much water has gotten into the cylinders. One had yellow foamy stuff in it. The others had dirt and trash in them. The space between the cylinder and the outside of the head had junk in it, looks like it was run in salt water and never cleaned. The wiring needs some work also. I am mechanically inclined and don't mind getting dirty doing the work but not sure if I should pay someone to do it. Should I rebuild it or chalk it up to leason learned?

I also noticed that the heads are not available on some sites and obsolete on other sites. How can that be?

From what you've said, I assume the engine does not turn over (seized). I'd suggest you remove the intake manifold assembly in order to inspect the crankshaft and connecting rods & bearings. If the crankshaft and rods are rusted, it's probably best to chalk it up to a lesson learned.

Note..... Applying heat from a hand held propane torch with a blow torch tip to the aluminum areas surrounding frozen bolts would help prevent the broken bolts scenario.

The 110 engine was superceded in 1990 by the 115. Basically the same engine. If you check, the heads for the 115 should still be availalble through Bombardier. 326504 and 326505. New replacement heads are not cheap. You may want to try to find some good used heads from a marine salvage yard.

I removed the intake manifold and still cannot see the crankshaft. I looks like the rebuild was the carbs and intake manifold because they look pretty good. The reeds look good as well. There was more of the yellow foamy stuff between the intake and the cylinder. I don't think there is much damage. I think I will clean what I can and replace the gaskets and reassemble everything and try to fire it up. What is your oppinion?

Re: 110HP Evinrude Mess

Are you thinking that the "yellow foamy stuff" is some type of storage preservative? If you have a concern, put some oil in the cylinders and rotate the flywheel by hand with the plugs out or the heads off. See what the cylinder walls look like. If you move the pistons side-to-side by hand-can you see if the rings appear to be free, or stuck to the pistons? You can try to start the engine. If it was put away (stored) with fuel in the carbs, you may find the carbs need an overhaul. If the old fuel dries up in the carbs, the passages get restricted and won't flow fuel properly.

Emdsapmgr, Thanks for the help. The carbs look to be in great shape. I am going to try to turn the flywheel by hand and see if it will work. After that if all is well I will try to start it. I have put some seaform in the cylinder. I will put more in before reassembly. I talked to a friend who has had many boats, he thinks it is some type of stabilizer. I will clean as much as possible.

Re: 110HP Evinrude Mess

It is possible the oily residue is fogging oil. That could be a good sign. Typically, you don't need to clean that out. When the engine is first started in the spring, that fogging oil will burn off inside the powerhead and down the exhaust midsection. It may take 15 minutes for that to happen-it will look like you are fogging mosquitos at first. Unless you have had the bowls off the carbs, hard to tell what those small passages look like inside. If it was fogged, likely the prior did the normal fall winterizing procedure, which should have included the carbs and fuel. I'd drain any remaining fuel and start with 100% fresh. These 2 strokes are finicky about fuel quality.
