Refer to the engine owner’s manual for

Fresh Water System
The entire fresh water system must be com-
pletely drained. Disconnect all hoses, check
valves, etc., and blow all the water from the
system. Make sure the water heater and fresh
water tank are completely drained. Use only
very low air pressure when blowing water
from the system in order to prevent damage
to components. The check valve mechanism
built in the fresh water pump will not remove
the water from the pump. Remove the out -
let hose on the pump, turn it on, and allow it
to pump out any remaining water (approxi-
mately a cupful).
Before storing your boat, the water system
needs to be drained and winterized.
WARNING
!
Hot water will cause burns. Do not
drain the freshwater system until
water in the water heater tank (if
installed) is cool.
CAUTION
!
Do not operate the water heater with-
out water in the water heater tank.
Failure to do so could damage the
water heater.
To drain the fresh water system:
1. Switch OFF the WATER HEATER
breaker on the AC distribution panel, if
installed.
2. Open all fresh water faucets (hot and
cold). Leave the faucets open.
3. Switch ON the FRESH WATER break -
er(s) on the DC distribution panel.
4. Allow the water to run until the tank
is empty. The tank is empty when all
faucets no longer produce a stream of
water.
5. Switch OFF the FRESH WATER break -
er(s).
6. Remove the hoses from the input and
output sides of the fresh water pump(s),
and let the pump(s) and hoses drain into
the bilge. The fresh water pump(s) are
located in the mechanical space.
7. Switch ON the FRESH WATER break -
er(s) for 3-5 seconds to remove the
water from the bottom of the pump hous-
ing(s). Turn OFF the FRESH WATER
breaker(s).
8. If installed, drain all water from the water
heater. Refer to section 5, Plumbing
Systems, and the water heater user
manual for the draining procedure.
Next, flush the system with potable water
antifreeze:
1. Close all fresh water system faucets.
2.
Reconnect the hoses to the water
pumps.
3. If an optional ice maker is installed:
• Disconnect the ice maker water sup -
ply and plug the supply line.
• Switch ON the ICE MAKER breaker
on the AC distribution panel.
• Allow the unit to run for an hour.
• Remove any cubes that may have
been ejected during this period.
• Switch OFF the breaker and prop the
ice maker door open to let the unit
defrost.
• After the ice maker has defrost -
ed, wipe it dry. NOTE: At no time
should potable water antifreeze
be allowed to enter the ice maker.
Follow the ice maker user manual
for winterization procedure.
