The following steps can be taken to protect your boat while in storage. Additionally, specific procedures recommended by the boat manufacturer should be closely considered.
Prepare your engine in accordance with the owner’s manual. In winter, this will normally include draining and flushing the cooling system; draining and refilling the crankcase; applying oil to the inside of each cylinder through the spark plug holes, and other preservative actions.
Thoroughly clean the hull, decks, cockpit, bilge, all compartments, lockers and the exterior of the engine, and coat with an appropriate wax or preservative.
Drain fuel lines, pumps, carburetor, and tanks or fill completely, and add fuel stabilizer.
Leave all floorboards up, doors ajar, ports and skylights open, hatches partly open, drawers and lockers open.
Carefully fit a well-made cover, provided with ventilation ports. If the boat is to be stored outdoors, make sure there are no low spots in the cover that will hold rainwater.
Place a cover over the engine. Do not leave the engine exposed to the sun or rain.
Don’t forget the trailer. Check tire pressure, and cover tires, if they will be exposed to the sun. Check and pack wheel hubs, if necessary, and lubricate jack.
Finally, note dates of registration, tags, certificates, and insurance, etc., and plan for renewal, if they expire during your storage term.
