i agree with bushwacker, I run the engine till it warms up and start spraying fogging oil in the carbs till the engine stalls out..then i pull the plugs and spray some more fogging oil on top of the pistons and hand crank the flywheel over one time..never had a stuck piston when i uncovered the boat in the spring, just looks like an airshow is in town when i fire up the engine to clear out the fogging oil. i also use engine cleaner and get as much salt off then spray some cpc on the engine.
