Seasonal Maintenance
Baitwell and Recirculation System
Install the baitwell drain plug and pour potable
water antifreeze in the baitwell until it covers the
intake for the recirculation pump. Then activate
the recirculation pump until antifreeze is visible
at the discharge fitting. Remove the drain plugs
and wipe down the inside of the wells.
Marine Toilet and Waste Overboard
Discharge System
Drain the discharge hoses completely using low air
pressure if necessary. The waste holding tank and
diaphragm discharge pump must be pumped dry
and two gallons of potable water antifreeze poured
into the tank through the deck waste pump out
fitting. After the antifreeze has been added to the
holding tank, open the overboard discharge valve
and activate the diaphragm pump until the anti-
freeze solution is visible at the discharge thru-hull.
The marine toilet must be properly winterized by
following the manufacturer’s winterizing instruc-
tions in the marine toilet owner’s manual.
Notice:
Make sure you follow the marine toilet manu-
facturer’s winterizing instructions exactly.
The freshwater supply line to the toilet must
be properly winterized when winterizing the
fresh water system.
14.5 Winterizing Bilge
Components & Engines
Bilge
Coat all metal components, wire busses, pumps
and connector plugs in the bilge with a protecting
oil. It is also important to protect all strainers,
seacocks and steering components.
The bilge pumps and discharge hoses must be
completely free of water and dried out when the
boat is laid-up for the winter in climates where
freezing occurs. Compartments and areas in the
bilge that will not drain completely should be
pumped out and then sponged until completely
free of water. Water freezing in these areas could
cause damage.
Notice:
The optional bow thruster and steering sys-
tems have specific lay up requirements. Refer
to their owner’s manuals for recommended
winterizing procedures.
Outboard Engines
The engines should be flushed with fresh water for
at least 15 minutes prior to winter storage. This
will remove salt, sand and other contaminates that
can damage the engine. It is also important to
“Fog” the cylinders, change the gear and crank -
case oil, coat each engine with a protector, wax
the exterior and properly store and charge the
batteries. You should refer to the engine owner’s
manual or contact your dealer for specific instruc -
tions on winterizing your engines.
Generator Raw Water System
Refer to winterizing the generator seawater cool-
ing system in the Raw Water System Winterizing
section of this chapter. Once this is accomplished,
you should refer to the generator owner’s manual
or contact your dealer for additional instructions
on winterizing your generator.
14.6 Preparing Exterior & Interior
Equipment For Winter Storage
Hardtop
It is imperative that all drain holes in the legs
are open and that the legs are completely free of
water. Remove canvas and thoroughly clean and
store in a safe, dry place. Remove all electronics.
Coat all wire connectors and bus bars in the helm
compartment with a protecting oil.
Clean the aluminum frame with soap and water
and dry thoroughly. Apply an aluminum metal
protector to the entire frame on anodized alumi-
num to reduce corrosion and pitting. Apply an
automotive or boat wax to powder coated alumi-
num to protect it during storage periods.
Towers
It is imperative that all drain holes in the tower
and hardtop legs are open and completely free of
water. Tower basket drains should be checked and
clear of debris. Remove the tower sun shade, if
installed, and belly band or removable cushions.
Then thoroughly clean and store in a safe, dry
place. Remove all electronics. Coat all wire con-
nectors and bus bars in the helm compartment
with a protecting oil. Cover the tower basket with
a tarp and secure it properly.
Clean the aluminum frame with soap and water
and dry thoroughly. Apply an aluminum metal
protector to anodized aluminum to reduce corro-
sion and pitting. Apply an automotive or boat wax
