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.

Check oil level in engine
Check primary fuel filter
Check cooling water level
Check sea strainer

Change engine oil and filter
Check V-belt tension
Adjust valves
Check electrolyte in batteries

Change engine oil and filter
Check air cleaner
Change primary fuel filter element
Check electrolyte in batteries
Check state of charge of batteries

Engine Symptoms and Diagnosis

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.

  1. Black smoke under load
    Dirty air cleaner, turbocharger problems, overload, over fueling Mostly fuel related problems
    We recommend changing air filters regularly, cleaning AirSeps annually (if installed)
  2. White smoke
    Leaking head gasket, cracked head, block or line, bad injector(s) Could be water related problems
  3. Unusual noise
    Bearings, 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.
  4. Lack of power
    Dirty air 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.
  5. High oil consumption
    Worn rings or liners, worn valve guides, worn bearings, worn turbocharger seals
    This type of problem should be rectified as soon as possible before leading to more serious engine problems.
  6. Increased fuel consumption
    Leak 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 consumption.
  7. Increased oil level
    Coolant 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.
  8. Overheating
    Cooling system problems, worn belts, plugged hoses, low coolant level, damaged or malfunctioning temperature regulator
    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.
  9. Hard starting
    Worn 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.
  10. Debris in the oil filter
    Excessive 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.
