Sample Maintenance Schedule


Regularly check that all watertight closures will keep water out.

  • Verify that closure devices - doors, hatches, windows, port lights, etc. - can be closed easily and completely. Check for warping, that gaskets are in good shape and that a complete seal is maintained.
    Lubricate mechanisms - latches, dogs - as necessary.
  • Check that water does not enter the vessel by spraying water directly onto closure devices using a hose.

Check that bilge alarms and pumps sound or turn on when activated. Weekly.
Taking care not to pollute, verify that the bilge pumping system or bilge pump(s) clear water from the bilges. At least annually.
Maintain painted surfaces and apply a light coating of oil every year to reduce corrosion. [are there pollution issues here?]  
Inspect and service transmissions and outdrive units according to manufacturer’s recommendations. Insert manufacturers recommended intervals
Pressure check outdrive units.  
Check transmission fluids and gear oil for water.  
Change transmission fluids and gear oil. Insert manufacturers recommended intervals and next due date.
Grease universal joint, gimbal bearing, propeller spline, and unit fittings.  
Check bellows and water seals and replace, if needed.

Clean and service outdrive unit.  
Verify that the steering gear has its full range of motion and that the gear moves easily, without being loose. Annually or as recommended by manufacturer.
Check anchor and cable/rope/chain for wear. At beginning of season.
Electrical System
Test all circuits for proper operation.  
Inspect all exposed wiring, fuse/ breaker panels and electrical equipment. Wire insulation should be intact and contacts and connectors should be secure and clean.
