Hello,

I just purchased a 1978 S2 9.2A with a Yanmar YSB12. I've seen very little
written on the engine, but expect reliable operation based on Yanmar's
reputation. What can I expect from this specific engine, good or bad?
What sort of crusing range/engine run time can I expect with 18 gallons of
fuel?

Thanks in advance.
