Protect your engine from startup wear with a small investment in prelube
The marine environment can be very hard on your engine. Boats and Ships routinely sit in port for weeks and even months between trips. During that time vital oil that is needed to protect the bearings and other moving parts of the engine drains back to the sump. Even after a short down time oil films can become very thin leaving the stage set for a bearing to "wipe". If direct metal to metal contact occurs during startup your engine is never the same. The damage caused by the first wipe will generate more friction and heat leading to progressive damage that could even leave you down an engine and far from shore.
Prelubing your engine every time you start it is the best way to be sure that oil is always protecting its moving parts. Compare the cost of a prelube system with the cost of engine overhaul and down time. It just makes sense to protect your expensive engine.
