BOAT MAINTENANCE

Keeping your boat in top condition will help eliminate mechanical problems which will in turn help prevent fires.
Nothing is more frustrating than having an engine problem at the dock or on the water. Good mechanical maintenance is the key to minimizing engine problems.

 A checklist is an excellent way to ensure you have inspected your boat, engine and trailer. Maintain all components regularly and inspect critical items frequently. Boaters are advised to keep the motor tuned, change the oil, and perform regular maintenance. If mechanical components fail, they must be replaced with marine grade components - never use automotive parts to replace marine engine parts.
A comprehensive inspection of the engine, associated electrical system, and fuel system includes checking the following items on a regular basis:

  • Through Hull Fittings – check the area around the fitting to ensure no water is leaking through the fitting. Inspect the packing around the fitting looking for cracks or splits.
  • Motor – inspect the area of the motor most likely to fail, which includes:
    • Belts - a properly adjusted belt should twist no more than ½ a turn. Look for cracks and abnormal wear. Replace at least every 500 engine hours or 3 years, whichever comes first.
    • Hoses - squeeze to check if they are brittle or soft. Replace at least every 500 engine hours or 3 years, whichever comes first.
    • Valve Covers – look for signs of leaking oil.
    • Distributor Cap, Spark Plugs and Wires
    • Carburetor – ensure backfire flame arrestor is securely attached, clean and an approved type.
    • Water Pump - look for a greenish discharge.
    • Alternator – check belt and inspect.
    • Expansion tank – look for signs of leaking.
  • Electrical System
    • Alternator
    • Battery – fully charged and in a proper storage container. Check cables often.
    • Battery Selector Switch – inspect wiring.
    • Bilge Pump – test frequently.
    • Navigation Lights – turn on and inspect all lights.
    • Engine Gauges - temperature, oil pressure, charging system, tachometer (engine RPMs).
    • Shore Tie Panel and Connections
  • Fuel System
    • Cap – securely fastened and of proper size.
    • Tank – inspect monthly for signs of deterioration or leaks.
    • Hoses – inspect for signs of wear or cracks.
    • Pump – look for signs of leaks
    • Ventilation Blower – check wiring and exhaust hoses.
    • Natural Ventilation – inspect intake and exhaust hoses.
    • Portable Fuel Tanks – insure they are secured and in good condition.
  • Vacuum Residual Oil (VRO) – provides the proper amount of oil to the fuel for an outboard engine which eliminates the need to add oil to gasoline for 2-stroke engines. Check for signs of leaking.

CHECKLIST FOR THE HULL, ENGINE, ELECTRONICS, AND TRAILER/VEHICLE

 

RED = Inspect before each outing

BLUE = Inspect regularly
   
1. Hull and through-hull fittings.
  Look for signs of structural weakness (stress cracks, gouges, chips, blisters, loose rivets)

  Unusual discoloring of the hull.
  Unusual amount of marine growth
  Cleats and tie-down points in good condition
   
2. Engine compartment.
  Check all hoses
  Inspect belts
  Look for signs of leaking oil or water (Even a small amount of fluid loss could mean major problems. Fix any leaks and replace any worn belts immediately).
  Check all fluid levels - oil, power steering, expansion tank, etc. Fill to manufactures specifications.
