Pressurized Water System
Note that the water system is non-potable (not for
drinking). If installed the pressurized water system
includes a deck fill plate, water tank, hoses, pressure
pump and sediment filter, head sink w/faucet and
transom shower.
The aluminum water tank is located in the forward
center bilge. The pressure pump and sediment filter
are normally mounted in the bilge. Periodically clean
the filter and screen if installed. Reinstall filter and
check for leaks.

Using Pressurized Water System
1. The tank capacity is around 16 gallons. Fill the
water tank at the deck fill plate. You might want to
use a white hose manufactured specifically for water
tanks. These hoses are available in 25, 50 and 100
foot increments at marinas, marine retailers, RV
dealers and big box stores. They do not leave marks
on the deck and do not carry a rubber odor. As you
look into the deck fill you may see a vent hole. With
this style fill plates once the tank is nearly full water
will emerge from the vent hole and re-enter the fill.
Shut the fill cap and line up the two dimples on the
cap and fill plate to seal the system from foreign
debris. You then can lock the cap by pressing on
the side of the cap handle.
2. At the helm switch panel activate the water
system switch. This will energize the water pressure
pump to send water from the water tank through
the cold water lines terminating at the head faucet
and transom shower.
3. Open the cockpit sink faucet.
Water pressure should be
present. Opening the faucet for
a few seconds will purge any air
in the system especially in cases
where the fresh water tank has run out of water.
When water is running at a faucet it is not unusual
to hear the water pump activate as it is trying to
build up the pressure required in the system. Soon
after the faucet is turned off the fresh water pump
sound will end indicating the water system is now
up to specified system pressure.
4. This entire water system is not
meant for consumption (non-
drinkable) and does not meet the
requirements of the U.S. Public
Health Drinking Water Standards.
This label found at the optional head and transom
shower is a reminder to passengers not to drink
the water. It is for cleaning or rinsing purposes only.
