Step 4: If your boat is equipped with a heater, shower or ballast bags, be sure to disconnect the hoses and drain any

remaining water in the lines to avoid freezing. Even small amounts of water in any of these areas can cause

signicantdamageuponfreezingandsuchdamageisnotcoveredunderwarranty!

Note: Be sure that hoses will not become entangled in the engine V-belt when the engine

turns over or the hose and/or the belt will be damaged.

Step 5: Useducttapetosealtheexhaustapstopreventdirtandnestingrodentsfromentering.

Step 6: Cover the boat with a boat cover or tarp.

Note: If the boat is to be stored outside and subject to accumulations of snow, water and

ice, a support should be made for the boat cover so that it will not sag, rip or tear, thereby al-

lowing water to enter the boat. Two-inch diameter PVC plumbing pipe is ideal for this purpose. It

is readily available at local hardware stores, and it is easy to work with. Also, its rounded shape

will prevent damage to the canvas.

Step 2: Charge and install the battery in the boat, following all safety precautions associated with changing batter-

ies.
