WINTERIZATION

A. Prior to Lifting for Winter Lay-up
1. Pump out the head (dockside discharge), and be
sure the holding tank is empty. Flush the head
holding tank with soap, water and a deodorizer
(e.g., Lysol Liquid™). Add more water if neces-
sary. Have the clean ing solu tion pumped out.
2. Have the fuel tank either full or completely empty.
See the Engine Owner's manual for recommenda-
tions. Also, check with the dry dock operators for
recom menda tions. If winter storing with a full fuel
tank, gasoline winterizer such as Sta-bil
condi tioner, will reduce varnishing, con den sa tion,
etc.
NOTICE
If the fuel has been treated with winter izer, run
engines for ten minutes to make sure the treated
fuel is present in all lines and parts of the engines.
3. Drain water from the fresh water system.
4. Before winterizing the engine, flush out the system
according to the specific engine owner's manual.
The engine flush out should be used to clean the
engine of unwanted salt, mud, sludge, etc. which
may have accumulated in the engine cooling
system.
5. Winterize the engine and drive systems as
recommended in the engine owner's manual
(applies to both gas and diesel systems). Portions
of this winteriza tion procedure may require that the
boat be lifted. Winterization of engine and boat
systems should be performed by qualified service
personnel. Note: Repairs and replacement costs
associated with frozen engine components are
quite substantial.
6. If the boat is to be lifted or taken off a trailer, see
Section P-7 - Hull Support in this manual for
additional details.
General Maintenance - Section R
B. After Lifting
1. Remove the drain plug.
2. Thoroughly wash the fiberglass exterior, espe c ially
the hull bottom. Remove as much marine growth
as possible. Wax lightly.
3. Lower boat onto cradle properly or place boat on
trailer (if applicable). Be sure boat is ade quately
support ed. The boat should be raised slightly
under the forward supports or trailer tongue to
im prove drain age to the transom drain.
4. Be sure all the water is completely drained from
the fresh water system. Disconnect all hoses,
check valves, etc. and blow all the water from the
system using very low air pressure. The use of
nontoxic, fresh water system antifreeze is recom-
mended as an alternative to disas sembling the
water system. Refer to Section J-5 - System
fuel
®
Maintenance in this manual for information on
winterizing the water sys tem.
5. Winterize the head (if equipped) as recommended
by the head manufacturer. If the boat is equipped
with a holding tank, mix some antifreeze solution
and pour it into the head. Trans fer some of the
antifreeze to the holding tank by flushing the head.
Also, refer to Section J-5 - System Maintenance
for addi tional information.
6. Ensure that all water is removed from the sump
pump, bilge pump and bilge pump lines. Dry the
hull bilge, and self-bailing cock pit drain troughs.
Water freezing in these areas could cause dam-
age. See Section K-2 - Hull Drainage Systems.
7. Remove the batteries and store in a cool place.
Clean the batteries using clear, clean water. Be
sure the battery has sufficient water and clean
terminals. Keep the batteries charged throughout
the storage period. DO NOT store the batteries on
a concrete floor or other damp or conductive
surface.
8. Clean the boat interior thoroughly. Vacuum
carpets, and dry clean drapes and upholstery
jackets as necessary.
9. Wash exterior fiber g lass components, wax lightly.
