9.1 Dockside Water Supply
When you are docked, you can connect a pressurized
dock water supply to your boat. A dockside water supply
will pressurize the boat's water system without using the
water pumps. The dockside system is connected after the
water pump which then will act as the check valve.
The dockside water inlet is standard on the transom.
Connecting a portable (drinking) water hose from a local
water source to this inlet provides water under pressure
to the fresh water system without using the pumps.
Dockside water often comes from a municipal water sup-
ply or similar sources which supplies water at a higher
pressure than the boat's onboard system pressure. The
pressure regulator on the water inlet reduces the pres-
sure of the dockside supply to match the boat system's
lower pressure which is normally around 35 psi.
This dockside water does not fill the water tanks.
Important: Always disconnect the dockside water supply when
you leave your boat unattended. A major leak or break in the
system could flood your boat. Excess water in the bilge may
sink your boat or flood the batteries and engine. Your warranty
does not cover this damage.
Note: Before you connect your boat's water system to the dock-
side water supply, make sure the dockside water supply is suit-
able for drinking. Check with the dockmaster to be sure.
9.1.1 To connect the potable water inlet to your
boat's water system:
1.Connect a drinking water hose to the potable water
supply.
2.Connect the other end of the hose to the potable water

spigot.
3.Open the cold water faucet closest to the potable water
inlet on the boat.
4. Open the potable water supply spigot. As soon as a
steady stream of water comes out of the faucet on the
boat. Close the spigot.
5. Check the boat's water system for leaks. This inspec-
tion is particularly important when you use the potable
water hookup the first time.
The fresh water system is now ready for use.

9.2 Water Tanks (on board water supply)

The fresh water system on your boat has three water
tanks totaling 140 gallons (530L) and three fresh water
fills located on the port midship, as well as one forward.
The vent for each tank is located on the side of the hull,
at each fill. There is an isolator valve which allows you
to select which tank is supplying water. (Fig. 9.1) See
the arrangement drawing at the end of this chapter for
locations.
Note: Whenever servicing the fresh water pumps, shut off the
DC breaker for the water system.
9.2.1 To fill the fresh water tank:
1. Make sure the potable water supply is suitable for
drinking. Not all potable water is drinking water. Check
with the dockmaster if necessary.
2. Open the water tank fill fitting. Fig. 9.1
3. Using the hose from the potable water supply, fill the
