Operate your genset once a week
If you don’t operate your generator and put it under load every week or so, bad things can happen. Injectors, for example, can shellac or get gunked up and the fins on the impeller in your raw-water cooling system can take a set, or become permanently deformed. If you don’t have time for a weekly crank-up, hire a mechanic to do the cranking. It’ll save you money in the long run.
