These generators are not designed to be powered from a propulsion engine
. They are AC generators and therefore require precise speed to produce 60Hz power. Modifying a propulsion
engine to have precise speed controls would be quite a bit of work
rating is class H. That means the insulation
can be 180C (350F). The ambient is specified at 40C so they are allowing for a 140C rise in winding temperature. At full load the housing will probably fry eggs (no joke).
Harmonic distortion is pretty common with these types of generators so that should be checked.
Realistically you have to wonder whether these generators will hold up in salt water
environments without a significant amount of work
. I would not put one in a boat
unless some few units demonstrated they were reliable at near full load for 2.5K hours without going up in flames. A couple of smoke detectors mounted nearby and wired to the fuel
cutoff would be mandatory.
Then there are those pesky ABYC standards which I won't get into.
Best advice I can give is to run away from this idea before the main engine gets broken or a fire breaks out.
