Note: This is a sample maintenance schedule only. Use it as a guide, and change the items and suggested timeframes to customize a maintenance plan for your vessel. Be sure to refer to the servicing recommendations by the manufacturers of the different vessel components.

Inspect and renew as needed. (anti-fouling bottom paint / topside cleaning / waxing) End of season
Inspect all through-hull fittings and attachments for leaks. Weekly
Check all through-hull fittings can be moved to closed position. Week 1
Check all above-deck watertight and through-deck fittings, including cleats, stanchion mounts, hatches, ports, doors, antenna mounts, and the hull to deck seal. Week 2
Check the cabin interior for water and stains, which could signal a leak and weak materials. Week 3
Change main engine and auxiliary generator oil and filter at the hours of operation interval recommended by the manufacturer or once a year, whichever comes first. Insert manufacturers recommended intervals, e.g. "Every 300 hours"
Check fluid levels. (oil, water, engine coolant) Daily
Check the engine(s) for oil or fuel leaks. Daily
(For gasoline powered vessels) Check the blower works properly and verify that the associated ductwork is free from leaks.  
Check that the bilge pump is operating properly and that the strainer inlet to the bilge pump suction is free from debris. When checking the pump, take care to not discharge a pollutant overboard.  
Tune up gasoline engines every year and replace electrical parts, such as spark plugs, as needed. Yearly
Inspect and tighten all hoses and drive belts often. Replace them when they are worn or cracked.  
Inspect the starter motor and alternator.  
Maintain painted surfaces and apply a light coating of oil every year to reduce corrosion. Yearly
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 from time to time.  
Grease universal joint, gimbal bearing, propeller spline, and unit fittings.  
Check bellows and water seals and replace, if needed.  
Check and replace the sacrificial zinc anodes on shafts, props, tabs, and other underwater gear, as well as engine-mounted zincs on the underside of exhaust elbows or risers and on the end caps of heat exchangers to guard against corrosion.  
Clean and service outdrive unit.  
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.  
Replace defective parts.  
Secure loose wiring.

Flush and chlorinate the fresh water system, taking care not to pollute.  
Check all fresh water lines and connections for tightness. Repair and/ or replace as needed.  
Check, clean and lubricate mechanical parts of all systems as needed for proper operation. These systems include hydraulic trim systems, air systems, anchoring systems, and bilge pumping and sanitation systems.  
Check safety equipment: lifejackets, flares, fire extinguishers, liferafts, life buoys, bilge pumps, oars, anchors, etc.  
Check radio equipment, EPIRB, antennas, batteries, and backup systems.  
Inspect and clean covers and upholstery.
