Winterization
When the boating season comes to a close, it is important to have your boat winterized by a service professional
or your local Supra Dealer.
If your boat is exposed to temperatures below 32 degrees F (0 degrees C), it is possible for water in the engine,
ballast system, etc., to freeze. As this water freezes, it expands and can crack pumps, valves, heat exchangers,
engine blocks, etc. This type of damage usually requires the replacement of the cracked item and can be very
expensive to repair.
It is extremely important to follow the proper winterizing procedure. The engine must be correctly winterized
for safe storage in your climate. This should be done by a professional. Your Supra dealer will know exactly
what must be done to ensure the longest possible life for your boat.
NOTE: During the winter months, water is a boat's worst enemy. Always store the boat when the interior is com-
pletely dry. Periodically check on the condition of the stored boat.
Damage due to improper winterization IS NOT covered under your boat's warranty.
E-10 fuels require fuel stabilizers that are specifi cally designed for E-10 fuels to help prevent moisture absorbtion,
phase separation and gasoline stabilization.
Winterization Continued:
In addition to having your boat professionally winterized, the following tasks should be done to protect your
boat during storage:
1. Remove the drain plugs from the boat.
2. Thoroughly clean the boat inside and out. Inspect the hull for any residue or algae growth and remove if
required.
3. Clean the bilge area thoroughly and operate the bilge pump to remove any water from the bilge hose.
4. Replace cushions and open all storage areas to air circulation in the boat interior. When thoroughly dry, re-
place cushions and close storage areas.
5. Top off fuel tank to prevent any condensation from accumulating in the fuel system. Use a commercially
available fuel stabilizer to remove water and prevent gumming.
6. If the boat is stored on its trailer, ensure that the boat is properly positioned. If possible, lift the tongue so
that the bow is slightly raised to promote drainage from the drain hole.
Install the canvas cover and secure the straps in accordance with cover instructions.
NOTE: It is recommended that the battery cables be disconnected from the battery when the boat is
placed in storage. BE AWARE, you will not be able to view telamatics information remotely when discon-
nected. (Refer to Battery Cable Installation and Precautions)
