Whenever possible after use in sea water or submersion in sea water, wash
entire engine with fresh water to remove salt deposits and wipe down with a
dry cloth. Spray entire powerhead with a liberal coat of Anti-Corrosion Spray
penetrant/lubricant or equivalent.
Though not specifically mentioned as a service procedure,
Anti-Corrosion Spray or equivalent should be applied after any service repairs
under the engine cover and repeated at regular intervals to protect powerhead
components. Anti-Corrosion Spray leaves a thin, non-messy, transparent film
that actually lifts water and moisture from metal surfaces. It protects
equipment and tools that are left outdoors, even in humid coastal areas. Anti-
Corrosion Spray dries out ignition systems to start wet engines and stops
moisture-induced short circuits in electrical systems.
