Winterization & Dry Storage
When the boating and ski season comes to a close, it is
important to have your boat professionally winterized.
If your boat is exposed to temperatures below 32 degrees F
(0 degrees C) it is possible for water in the engine, ballast
system, heater core, 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.
In addition to having your boat professionally winterized, the
following tasks should be done to protect your boat during
storage:
1.Remove the drain plug 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.Remove all seat cushions and open all storage areas to
air circulation in the boat interior. When thoroughly dry,
replace 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, insure 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.
7.Install the canvas cover and secure the straps in
accordance with cover instructions.
NOTE: During the winter months, water is a boat’s worst
enemy. Always store the boat when the interior is
completely dry. Periodically check on the condition of the
stored boat.
Damage due to improper winterization IS NOT covered
under your boat’s warranty.
Before using the boat after it has been in dry storage
requires some special treatment. Supra recommends
having your boat professionally summerized, preferable
by the same facility that prepped it for storage. They will
be familiar with what items were done in the fall and what
items need to be addressed in the spring.
In addition to having your boat professionally summerized,
the following list of tasks should be done to ensure a
successful start to your boating season.
When launching the boat for the first time of the season,
carefully watch all gauges to ensure that the boat is not
overheating, the alternator is charging and the engine has
proper oil pressure.
