I have a siezed Yanmar
YSM12 in my boat. I want to rebuild
it, and am trying to line up a source for parts
before I begin the job. I am pretty sure I will need new rings and a cylinder sleeve, and bearings, as well as gaskets, and then some. Yanmar
dealers I have spoken to tell me that parts
are no longer available through them.
Has anybody had experience using parts from any other Yanmar motors to fit a YSM12? A friend suggested a YSB might cross over. I know Yanmar made a lot of agricultural diesels, and perhaps my engine
was sold for agricultural machinery under a different name.
Also, those who have had a YSM12, how badly does this engine
vibrate in use? Is there any other significant pros or cons to this model?
I have found the Boy Scouts' manual and a little bit more on the net, but I am pretty much in the dark on this Yanmar, and any information will be appreciated.
