I have an SL-3 I am going through now, hooked to a 7.5kw marine generator. I know about the carbon issues with these engines, and it most likely will be used to charge a large bank of batteries so it won't be running at partial power very much. I am also considering turbocharging and hooking it to a larger generator, but that is a ways off.
The idea I am running around with now is to set up a ~250gallon heating oil tank with insulation and a heater, fill it with WVO, and use that to fuel the generator. I do plan on being many miles off grid, so this will be my primary source of power.
Anybody have long-term experience with this engine on WVO?
