that there are no cracks in any exhaust system
component that would allow carbon monoxide
gases to escape.
FRESH WATER COOLING SYSTEM
Fresh water cooling systems, also known as closed
cooling systems, help protect engines from internal
corrosion and provide more even distribution of engine
temperature. Be sure to change the coolant annually.
OIL CHANGE SYSTEM
Your Chaparral boat may be equipped with an oil
change system located on the inboard port stringer
at the center of the port engine. The system simpli-
fies changing the oil in the engines, transmissions,
and generator. The pump is self-priming and pumps
in either direction. The oil change pump is protected
by the OIL CHANGE PUMP breaker on the DC
breaker panel on the aft bilge component board.
Important: Be sure to have only one valve open
at a time. Make sure other valves are closed to
prevent accidental overfilling.
Operating Instructions
Important: Be sure to service one engine at a time.
1. Before starting, run the engines or generator for
several minutes to warm the oil and mix the
sludge.
2. Turn OFF the engines.
3. Select the first engine to be serviced. Turn the
valve to the OPEN position, in line with the
valve body.
4. Turn the pump ON (switch position indicates the
direction of flow) and pump the old oil into con-
tainers. Dispose of properly offshore.
5. Once the oil has been pumped out of the unit,
place the pump discharge hose into a container
of pre-measured fresh oil and reverse the pump
switch to pump the fresh oil into the engine.
Note: Fresh oil should be at least 60°F (16° C)
6. When pumping is complete, shut the pump off
and close the valve leading to the unit being serv-
iced. Check the oil level and adjust if necessary.
7. Repeat for each engine, generator or transmis-
sion to be serviced.

INSTRUCTIONS AND WARRANTY INFORMATION.
SEACOCKS AND STRAINERS
Your boat is equipped with seacocks and strainers
to provide cooling water to the engines, generator,
and A/C units located throughout the bilge area.
To open the seacock, turn the handle in line with the
water flow (vertically). To close, turn the handle
against the water flow (horizontally).
Note: Be sure to close the seacocks when your
boat will be unattended for extended periods.
Inspect and clean sea strainers regularly. The fre-
quency of cleaning will vary depending on the
amount of use and local conditions. If operation of
the air conditioning is excessive it is important that
the A/C unit strainers are inspected more frequently
than other strainers.
The seacock body should be inspected and
lubricated annually.
