In reality, the engine is so reliable and trouble-free that the only thing you really need to worry about is the quality of the fuel. My primary fuel system is Racor's turbine diesel filter system. This system is self-priming from the main tank and has a vacuum gage for filter replacement. In 10 years I have never had to change the secondary fuel filter located on the diesel engine. The entire system has been very reliable, efficient and trouble-free.
Maintenance is negligible and is easy to perform when necessary.
The Yanmar steers with the rudders, handling around the docks is a breeze. Everything has always worked the way it is supposed to. 120 Volt shore power is provided through a 50 foot 30 amp cord. Battery charging is automatic when on shore power or through a large alternator on the Yanmar. Again, everything is factory fresh, convenient, and works the way it is supposed to.
