block the small DC currents that flow in seawater between boats in
a marina because different metals on the boat are in the water.
When the shore power cord is connected to boat and breaker, the
green light on the panel should be on.
FUEL SYSTEM
The internal fuel system on your Chaparral boat meets all current
Federal requirements.
Fuel lines, filters, and all fuel system components should be
checked at the start of each season and periodically thereafter, par-
ticularly after any work has been done aboard the boat which might
have affected any part of the system. Be certain that all are in
proper condition and that the entire system is fuel tight.
The fuel tank is located forward of the engine compartment under
the cockpit floor. The fuel tank fill pipe is located on the outside
deck. Some models have a dual fuel system, providing convenience
and flexibility of refilling your fuel tank from either side of the boat.
The fuel tank vent allows air to escape as the tank is being filled and
helps equalize tank pressure as temperatures change. The tank
has an anti-siphon valve which keeps fuel from leaking into the boat
in case of fuel line breaks.
Periodically, check the condition of the fuel tank components. Fuel
tank fittings are accessible through the inspection plate of the cock-
pit floor.
Note: The fuel fill cap has a built in tank ventilation feature. If
you should need to replace the cap, see your Chaparral dealer
for the exact cap to ensure proper fuel system operation.
Fuel Recommendations:
The quality of the fuel is very important for satisfactory engine per-
formance and long engine life. Fuel should be clean and free of
contamination. Your fuel tanks should be kept full of fuel whenever
possible. This will reduce the amount of water condensation and
reduce the possibility of contamination
FRESH WATER SYSTEM
The fresh water system provides water from an onboard storage
tank. Figure 3.3 shows a typical system and its components. A hot
water heater can provide hot water to the fresh water system. Before
using any fresh water system component, the water pump breaker
switch on the DC electrical panel must be switched on. When using
the shower in the head compartment, be sure to switch on the sump
pump switch (if so equipped) on the DC electrical panel, to activate
the automatic sump pump connected to the shower drain.
The fresh water tank is filled through the fill plate on the side of the
deck. The tank vent is next to the fill plate. The vent allows air to
enter and escape as water levels change. Fill the tank only with
potable water. Using and refilling the tank frequently keeps drinking
water fresh and clean.
Some models are equipped with an optional dockside water inlet.
This allows city water to be connected to boat while at dock.
Note: Do not leave boat unattended for extended periods with-
out disconnecting dockside water.
