CHAPTER 12
ROUTINE MAINTENANCE
12.1
Refer to the following chart as a general guide but not the gosple for routine maintenance actions
on the engines installed in your boat.
Refer to the engine manual
for the complete instructions on each
item. 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 engines are assumed – check your
manuals if your brands differ.
