intervals should be directly correlated to type of usage. If an engine
is only run intermittently (e.g., start the engine
, pull away from the dock
, hoist sails
, kill the engine, go sailing, start the engine, drop sails
and pull into the slip) then the engine will require more frequent oil
changes. On the other hand, if you're motoring from non-stop from San Diego
, you'd probably not need to change it until you arrived.
Remember, for the most part, engines in cruising sailboats have it very easy. Rarely do they run for extended periods at full throttle, full load. They're in a virtual dust-free environment
and they have entire oceans to provide cooling
. Add to all of that owners who continuously fuss and fret over their little-understood engines. Diesel
engines are largely extremely reliable even when forced to work under harsh conditions with poor maintenance
. Modern lubricants and highly-effective filters means that rarely will an engine develop lower end (crankshaft, connecting rods, cylinder walls, pistons, etc) problems even if it has a modicum of service
Fair winds and calm seas.
