Perform all maintenance once a year even if hour levels have not been reached. Some of the
items you may choose to leave to professionals, but many you can do yourself. In particular, it is
a good idea to have a certified mechanic perform check-ups from time to time on the engine,
generator, and any other key equipment installed onboard. Volvo Penta & Northern Lights
