Basic Maintenance Schedule
The schedule will vary from manufacturer to
manufacturer, but below is a very basic outline of what you can expect for a
typical maintenance schedule.
Engine Symptoms and
Check oil level in engine
primary fuel filter
Check cooling water level
AFTER FIRST 50 HOURS:
Change engine oil and
Check V-belt tension
Check electrolyte in
EVERY 100 HOURS:
Change engine oil and
Check air cleaner
Change primary fuel filter element
electrolyte in batteries
Check state of charge of batteries
Below are a few
symptoms and suspected diagnosis. These are merely based on often seen problems
and may have underlying causes that require closer inspections.
- Black smoke under
cleaner, turbocharger problems, overload, over fueling — Mostly fuel related
We recommend changing air filters
regularly, cleaning AirSeps annually (if installed)
- White smoke
Leaking head gasket,
cracked head, block or line, bad injector(s)— Could be water related
wrist pins, turbocharger or injectors — Hard to self-diagnose
This will require a sea trial with someone to navigate
the boat, while the mechanic inspects the engines. The problem may not be
engine related at all, it could be drive train related.
- Lack of
cleaner, dirty fuel filter, governor out of adjustment, injectors
malfunctioning, bad fuel
Regularly changing air
filters and fuel filters will eliminate the most common problems. This could
also be a dirty bottom or propeller.
- High oil
rings or liners, worn valve guides, worn bearings, worn turbocharger
This type of problem should be rectified as
soon as possible before leading to more serious engine problems.
- Increased fuel
in fuel system, dirty air cleaners, poor operation
Installation of Floscan monitor to monitor fuel usage is
recommended. A barnacled bottom or propeller could also cause increased fuel
- Increased oil
leak, accidental overfilling
Filling oil when
engines are cold will cause overfill when oil heats and expands. If water is
present the oil will be obviously off color.
Cooling system problems,
worn belts, plugged hoses, low coolant level, damaged or malfunctioning
Any salt water system
should be periodically flushed, especially heat exchanger due to build up of
salt in the system which causes diminished water flow and higher temperatures.
injector pump, low cranking speed, poor quality fuel, plugged fuel line or
filter, battery problems
Usually determined by
the sound the engine makes when trying to start among other clues.
- Debris in the oil
bearing wear, damaged internal parts, coolant or fuel leaks into the
crankcase, extended oil drain interval, improper oil, additives
We recommend an oil analysis on a regular basis to find
symptoms early enough to correct before they lead to more serious problems.
