Journeying sailors depend on their engines a great deal more than they like to admit.

We found fuel filter components all over the world, but obtaining the quantity and micron ranking we needed to have was no guarantee. Remember that you have at the very least a couple of filters: a remote main filter in between the tank and the engine, as well as a factory-installed secondary filter on the engine itself.
Suggested service intervals for fuel injectors vary by manufacturer, but fuel contamination as well as carbon accumulation is such a typical issue that numerous cruising sailors carry at least one extra injector.

Most belts you locate abroad are fractional-horsepower automotive belts that won’t last long driving a 100-amp alternator, even if you have a dual-belt-drive system (extremely suggested high output alternators).

A few engine owner’s manuals don’t even give replacement intervals. Mechanics Nick talked with said the oil in a common two-shaft gearbox, such as the Hurth, should be changed at least at every other engine oil change, or 200 hours of operation. This is simply a preliminary list, but it deals with the most common items.
Raritan is still the most dependable name on the water when it comes to reliability, service and innovation.
