• Pump out the holding tank.
Water System
• Turn ON the WATER SYSTEM switch.
• Open the water faucet and let the system drain
completely.
• Turn OFF the WATER SYSTEM switch.
• All water must be removed from the water lines
with air pressure or by flushing with a nontoxic
antifreeze.
Using Pressurized Air To Remove Water From
Water Lines:
• You must have an air compressor with an air
hose and air nozzle.
• Remove water hoses from the water pump.
• Alternate opening one faucet at a time to make
sure that water is removed from each line.
• Blow air through the water lines removed from
the water pump.
Note: When blowing air, be careful not to blow
air when all of the faucets are closed. The sys-
tem could be damaged by over pressurization,
ultimately creating water leaks.
• Cover the ends of the hose with a screen or
broad weave cloth, and tape in place to keep out
dirt and bugs.
Using Nontoxic Winterizing Antifreeze:
• Purchase a nontoxic winterizing antifreeze for
fresh water systems from a marine or RV supply
retailer.
• Close all faucets and turn on the water system.
• Open one faucet at a time. Close when non-
toxic antifreeze comes out of faucet.
• After all faucets and showers have been treated,
open all faucets and pump out remaining non-
toxic antifreeze.
Water Heater Winterization
Refer to your water heater Owner’s Manual for
detailed information on preparing the water heater
for storage and winterization.
Fuel Systems
• Add diesel and recommended amount of bio-
cide, such as “Biobor
®
”, to the fuel tank. Biocide
will prevent bacteria and fungi from contaminat-
ing diesel fuel that contains some water.
• A petroleum distillate additive, such as “Stabil
®
”
or “Racor
®
RX100”, should be added to diesel
fuel. This additive will absorb water in the fuel
and prevent freezing problems.
• Run engine(s) for ten minutes to ensure that all
diesel fuel in the injectors and fuel lines is treated.
Note: Detailed winterizing, operating instruc-
tions and warranty information are provided by
the equipment manufacturer and can be found
in the owner’s packet.
RECOMMISSIONING
Note: For detailed information on recommis-
sioning your boat’s systems and equipment,
refer to the owner’s manual for each system or
component.
Fuel System
Inspection of the fuel system at recommissioning is
very important. We cannot overemphasize our con-
cern for your safety.
Inspect, visually and by smelling, the fuel system and
all associated components for proper connections,
wear, leaks, or other damage and needed repair.
