I usually have items in the refrigerator and the freezer.
410's, 400's, 380's, 330's etc. come equipped from the factory with dual-electric (AC/DC) fridges and don't need the generator to keep the beer and cheese cold. (unless someone has replaced the OEM unit with an AC-only one)
Icemakers are AC-only, but most generators will burn about $25 in fuel to make ice that you could buy in the store for $1.50.
I have to make an effort to keep a load on the genny, but it has proven to me repeatedly that a load is necessary.
Bob,
During extended cranking, the belt-driven impeller is pulling in water that needs exhaust pressure to be expelled out of the muffler. If the engine isn't firing, the exhaust could eventually fill to the point where ingestion occurs. The Westerbeke manuals DO suggest that the seacock be closed if extended cranking is required.
