The following checklist
for laying up your boat is adapted from Nigel Calder's invaluable Boatowner’s
Mechanical and Electrical Manual (Model 420323). For more information,
including how to winterize generators, air-conditioning units and sailboat
rigging, see Appendix A in his book.
Engine and Gear
- Change the engine
oil, transmission oil and antifreeze.
- Drain the raw-water
system, taking particular care to empty all low spots. Remove rubber
pump impellers, lightly grease with petroleum jelly and replace. Leave
the pump cover screws loose so that impellers won't stick in the pump
housings. Run the engine for a few seconds to drive any remaining water
out of the exhaust. Wash salt crystals out of any vented loops.
- Check the primary
fuel filter and fuel tank for water and sediment. Keep a diesel tank
full to cut down on condensation.
- Squirt some oil
into the inlet manifold and turn the engine over a few times (without
starting) to spread the oil over cylinder walls.
- Grease all grease
- Remove the inner
wires of all engine control cables from their outer sheaths; clean,
inspect, grease, and replace. Check the sheathing.
- Seal all openings
into the engine (e.g., air, inlet, exhaust) and the fuel tank vent.
Put a conspicuous notice somewhere so you remember to unseal everything
at the start of next season.
- Inspect all hoses
for signs of softening, cracking and/or bulging.
- If hauling out:
Check for propeller blade misalignment and Cutless bearing wear; tighten
any strut mounting bolts; inspect stainless steel prop shafts for crevice
corrosion; remove prop nut to check under it.
- Bring to a full
charge. Equalize wet-type batteries. Top up. Clean the battery tops.
Unless the batteries are being properly float charged (via a solar panel
or battery charger with float regulation) remove from the boat and store
in a cool, dry place. Bring wet-type batteries to a full charge once
- Remove electronic
equipment to a warm, dry place.
- Clean corrosion
off all electrical terminals and connections and protect with petroleum
jelly or a shot of WD-40 or other moisture-dispelling aerosol. Pay attention
to all external outlets, especially the AC shorepower socket.
- Drain and/or pump
system with 30% to 50% antifreeze. Break loose the discharge hose and
check for calcification. Wash out vented loops.
- Pump out and clean
tanks. Drain system and/or pump through a 30% to 50% propylene glycol
antifreeze solution. Use a water-heater by-pass, if applicable. Inspect
pumps (especially vane and flexible impeller types) for wear. Remove
flexible impellers, lightly grease (with a Teflon-based grease), and
- If hauling out,
repack. If wintering in the water, tighten down to stop any drip. Be
sure to loosen before reusing the propeller or the shaft will overheat.
- If hauling out,
pull and grease all seacock plugs if possible. Dismantle and grease
gate valves. If wintering in the water, close seacocks (except cockpit
drains) and closely inspect cockpit-drain hoses and clamps.
- Drain a little
fuel from kerosene and/or alcohol tanks and check for water and contaminants.
Close LPG or CNG gas valves at the cylinder. Renew filaments on filament-type
igniters at least every two years.
- Cable steering-remove
cables from conduits; clean, inspect, grease, and replace; check sheave
mountings. Cable steering-clean, inspect, and lubricate cable ends.
Rack-and-pinion steering-remove top plate and input socket screws; clean,
grease and replace. Hydraulic steering-top off fluid and check all seals
and hoses for leaks and/or damage.
