Winterization and Storage
12-3
• The cradle or blocks must be on a hard, level surface capable of supporting the
combined weight of the cradle and the boat.
• When using blocks with jack stands, always use jack stands that are rated for
more than the required load, making sure they are securely positioned so they
cannot move under the load. Use a minimum of three blocks to support the keel
and each side of the boat where applicable. Use a minimum total of nine jacks
and/or blocks.
• Position the boat to allow for adequate draining from rain or snow.
• Cover the boat to prevent the collection of rain, snow or debris. When using a
cover, allow ventilation for residual moisture and condensation to escape. Never
cover or plug the boat bilge drain hole.
STORING ON A TRAILER
• Ensure the trailer supports are adjusted to properly support the boat’s hull.
• Repack the trailer wheel bearings with water-resistant wheel bearing grease.
• Park the trailer and boat in a protected area to reduce possible damage from
the elements and surroundings.
• Loosen the tie-downs and winch line and ensure the boat is resting properly on
hull supports.
• Lift the trailer and place blocks under the trailer frame to relieve weight on trailer
tires and springs. Position the boat to allow for adequate draining from rain or
snow.
• Cover the boat to prevent the collection of rain, snow or debris. When using a
cover, allow ventilation for residual moisture and condensation to escape. Never
cover or plug the boat bilge drain hole.
RECOMMISSIONING AFTER STORAGE
• Remove blocks from under the trailer frame.
• Tighten tie-downs and the trailer winch line.
• Check tire pressure and lug nut tightness on the trailer.
• Inspect the hull for damage.
• Charge and install all batteries.
• Check the bilge blower vents for obstructions and blower operation.
• Check the bilge pump and float switch for proper operation.
• Inspect all battery and electrical wiring for loose connections and/or damage.
• Check the fuel system for leaks or damage.
• Check the engine and bilge for signs of nesting animals; clean as necessary.
• Check entire engine for cracks and leaks caused by freeze damage.
• Check the condition of all hoses and clamps for tightness.
• Clean the bilge area and install the boat bilge drain plug.
• Lubricate all seacocks and check for proper operation.
• Install all drain plugs in strainers and seacocks.
