9.1 Water Tanks (on board water supply)
The fresh water system on your boat has one water tank
totaling 75 gallons (284L) and one fresh water fill (Fig.
9.1) located at the bow. The vent for the tank is located
on the side of the hull, at the fill. 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.
9.1.1 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
tank until water starts flowing through the vent.
4. Close the fill fitting.

Always ensure that when filling the fresh water tanks
that you are filling through the fresh water fill. Other
fills or pump outs may visually look the same. Filling
fresh water in to the waste pump out could flood
your boat, or filling the diesel fuel tank could dam-
age your fuel system.
9.1.2 Fresh Water Sanitation
NOTE: Be sure and read the OEM manuals that are supplied
with your boat, the next section is taken from one of those
manuals.
Sanitizing Potable water systems require periodic main-
tenance to deliver a consistent flow of fresh water.
Depending on use and the environment the system is
subjected to, sanitizing is recommended prior to storing
and before using the water system after a period of stor-
age. Systems with new components, or ones that have
been subjected to contamination, should also be disin-
fected as follows:
NOTE: The sanitizing procedure is in conformance with the
approved procedures of the US Public Health Service.)
1. Use the following methods to determine the amount of
common household bleach needed to sanitize the tank:
A. Multiply “gallons of tank capacity” by 0.13; the result
is the ounces of bleach needed to sanitize the tank (30
gallons X .13 = 3.9 oz bleach).
B. Use the number of liters of tank capacity to determine
the number of milliliters of bleach needed to sanitize
the tank (120 liters of tank capacity = 120 milliliters of
bleach).
2. Mix into solution the proper amount of bleach within a
container of water
3. Pour the solution (water/bleach) into the tank and fill
the tank with potable water.
4. Open all faucets (hot and cold) allowing the water to
run until the distinct odor of chlorine is detected.
5. The standard solution must have four (4) hours of
contact time to disinfect completely. Doubling the solution
concentration allows for contact time of one (1) hour.
6. When the contact time is completed, drain the tank.
