I was the proud owner of a YSM12, a one lung, raw water cooled beast
that snapped engine mount studs as frequently as some people change
their underwear.

Finally had to install an AquaDrive system to isolate the engine from
the boat hull and eliminate the snapping studs problem.

Little did I realize until much later that Yanmar had withdrawn the
YSM12 from the marine market and my builder had evidently picked up my
engine at a close out sale.

Had the boat 11 years, and that YSM12 was a PITA the entire time.

Today's Yanmar product is a high RPM, low weight unit designed for the
power boat market, not a low RPM, high torque unit designed for a
sailboat application.

Yanmar has figured out the the power boat market spends money and the
sail boat market talks everything to death, but doesn't spend any
money.

I have a friend with a YSM12 in his 27' sailboat. He installed it
himself so maybe he does not have stock mounts. My old 1GM broke a
mount but I never got around to fixing it for 9 yrs and never had
another prob with it. That little engine sounded like the African
Queen but in 9 yrs started EVERY time no matter what. It was also
very easy to work on. I thought it was a great piece of engineering
but at 6.5 hp, a little small for my 7700 lb S2. So, I found a use
2GM (13 hp) and I think it is also wonderful (installed it myself). I
admit, this is only two data points.
