I have a Yanmar SB12 single cylinder, 12 hp, water cooled, diesel for sale. The engine is in great condition but failed because of a bent rod. I have since replaced the engine with another engine. I'll throw-out a few to be used as keywords - water pump, impeller, head, piston, rings, transmission, oil pan, fuel injector, ALL the banjos, gears, etc. Many of the parts are interchangeable with the YSE, YSB, and SB8 Yanmar's too so keep that in mind.
Let me know what part(s) you need.
