FUELING THE BOAT
Filling the Tanks
1. Always fuel in an area with sufficient lighting.
Gasoline spills are difficult to see when lighting
is poor or when it is dark.
Important: When fueling your boat, be sure the
waste or water fill caps are not mistaken for the
fuel fill tank. Fuel fill plates are located on the
port and starboard aft gunwale (Figure 4.1).
2. The Chaparral boat has fittings for filling the fuel
tank. Remove the fuel fill plate. Insert the fuel
supply nozzle. Allow the nozzle to stay in contact
with the fitting to prevent possible static-pro-
duced sparks.
3. After pumping approximately 5 gallons of fuel into
the tank, inspect the engine and fuel tank area for
any signs of fuel leakage. Continue fueling if you
do not detect any leaks or other problems.
Note: Do not overfill tank, as this will cause fuel
to spill onto the water. Listen as the tank fills
and stop adding fuel before it spills from the fuel
fill opening.
4. Know your fuel capacity and consumption.
Record the amount of fuel used since your last fill
up, and compute the engine’s hourly fuel usage.
To determine a backup check, deduct the aver-
age hourly fuel usage from the fuel tank capacity.
5. Observe the Rule of Thirds: one-third fuel for the
trip out, one-third for the return, and one-third for
reserve.
6. Allow an additional 15 percent reserve when
operating in rough waters.
Post-Fueling Procedures
1. After fueling, replace the fuel fill cap. Do not
wash spilled fuel overboard, but mop up any fuel
spillage around the fuel fill area with rags or
paper towels. Dispose of them properly on shore.
2. Open the engine compartment and all hatches,
windows, doors, and compartments that were
closed during fueling. Visually inspect these areas
for fuel line leakage and smell for fuel fumes.
3. Check out any sign of fuel leakage or any indi-
cation of fumes and correct the problem before
starting the engine.
STARTING THE ENGINES
The following information is only a general guide.
Detailed engine operation and maintenance infor-
mation that describes pre-start and starting proce-
dures can be found in the engine owner’s manual.
Be sure to read and follow all instructions.
1. Check all fluid levels before starting the engines.
2. Check the fuel supply to make sure that you
have adequate fuel for your planned excursion.
3. A blower switch is located in the DC cabin panel
area. Run the blowers for four minutes prior to
starting the engines.
