Heck, I'm interested in that 2-stroke running a generator idea...

I've been tempted to try that for a large (52") cruiser/drill rig tender I've got... it has lots of weight allowance (needs 2 kilos of ballast in addition to the two motorcycle batteries that it uses for power. And before anyone argues it'd get lighter as it burns off the fuel, if you make a double-chamber fuel-balast unit, as the fuel bladder shrinks in a sealed chamber (like an IV bag in a ABS tube) it sucks in water and maintains the ballast.

Please, tell us more about the powerplant!
