It'll probably run out of oil now.

Re: Yanmar 1GM10 runaway?

It's odd though, I'm sure the level has gone up, I can't imagine I misread it consistently. Absent any diesel, the only other place that contains anything fluidy is the transmission.

Re: Yanmar 1GM10 runaway?

Oh and I forgot to say, it was maybe 1/4" above the max line.

Re: Yanmar 1GM10 runaway?

Paul- I would suggest an oil analysis. It's possible that you are getting diesel into the lube oil, there aren't too many other ways that the level can go up. You might be able to tell if it's diesel contamination by the feel test, suck some oil out of the engine and compare to fresh oil between your fingers.

Re: Yanmar 1GM10 runaway?

I'll do a quick paper check next time I'm at the boat.

Re: Yanmar 1GM10 runaway?

Well, I tried the paper test on the oil, it looked pretty much like number 2 on this diagram, oily coloured blob with a very slight clear edge which would indicate a lack of diesel in the oil.



All very odd, I checked the oil level again and it was where I left it Sunday, about 1/4" below max (looks like had I only taken out about 200ml then it would have been bang on max). Don't know, maybe I had a bit too much oil in there (but not by much) and it just misted that up to the intake which eventually hit the sweet spot for self accelerating behaviour.
Oh well, I think I'll just keep an eye on things and see how it goes.

Maybe make up something you can easily block off the air flow with, a rag, plug, or plate? I have read a CO2 extinguisher may work?

Maybe wear some body armor & a helmet before going below to fix the runaway?

Re: Yanmar 1GM10 runaway?

Nice thing about the little Yanmar is there is a decompression lever right on the top within easy reach. The air intake is a little bit tough to get to when the engine is screaming away.

No hands on experience with Yanmars, but I think I have read not to use the decompression lever(s) to stop the engine, something about the valves?

Re: Yanmar 1GM10 runaway?

Yeah, that decompression lever just pushes one of the valves (the exhaust I guess) down a little bit. I can't see trying that while the valve is pounding up and down.
