Re: Wash my engine out after my ocean trip or not?
Always flush all my engines after use in salt water, the ones who lives constantly anchored at sea will develope more corrosion in interior parts as in crankase, block, head, around head gasket, water passages, salt layer formation or crust formation in thermostat area and sometimes lessening diameters of all internal water passages, which lessens best refrigeration, worst if engines are used commercialy on daily basis.
No matter how well you flush your engine salt formation will start to develope in microscopic thin layers through it's use, so it's a good idea depending on the engine model to tear head down periodically each 300-500 worked hours, clean all water paths, thermostat area, place a new head gasket, torque to specs. That way engine will last much longer and perform, refrigerate nicely as when it was taken out of the box..
