I'm seeking a small engine that can drive a generator.
By small, I mean in the 12"^3 range.

It must be 4 cycle as it will need to run on propane.
It will drive a 13.8V generator, or 120VAC, say 800 watts.

If H-F Item#63025 was 4 cycle, (and it was un-junk....) that
would be ideal.

This to fit aboard a sailboat for stationary power/starter
battery recharging.

Of course, if instead you have a Diesel in that size [Ha!],
speak up.


If you meant 12" x 12" x 12" then possible

or
one of the small Honda generators which have a good reputation but
aren't exactly cheap. There is also a "Robin" look alike that is
cheaper but I don't know the quality.

Depending on the size of the boat you might look into solar panels. I
used them on a 40 ft. boat for a number of years and while they didn't
supply all the power I used they did prolong the time between battery
charges :-)

As an aside, all of the really small generators I've seen had a "hot
exhaust" and shouldn't be used in closed quarters.
The ROBIN motor is made by Subaru and sold as a Wisconsin,
