I don't think there ever were any "stock" mounts. If it worked, it worked.

That little engine sounded like the African
Queen but in 9 yrs started EVERY time no matter what.

You betcha. Thought about Hepburn and Bogie everytime that little beast was
at idle.

Could point upstream and idle in place against about a 1-2 knot current at
less than 1,000 engine RPM..

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.

Nice boat.

So, I found a use

2GM (13 hp) and I think it is also wonderful (installed it myself).

Different engine.

The YSM8/12 were great inustrial engines, not so great as marine units.

The points remains that today's Yanmar product line is a light weight, high
RPM family much like the old VWs.

Works well in a hight speed power boat, not so well in a sailboat which
needs high torque, low RPM.

The 1GM and 2GM do have stock mounts with huge rubber flex pads.
When I bought my S2 with the 1GM, i was worried about being able to
power into thunderstorms (we have a lot of them here in N. FL) so I
had the 2 blade prop replaced with a 3 blade and it seemed to work
well. I once ran from Naples, FL to St. Marks FL no wind at all the
entire time for 250 miles and burned only 12 gallons of fuel at 5 kts
the whole time. That little engine never missed a beat.
