6.
After pumping approximately 10 gallons of fuel into the
fuel tank, inspect the engine and fuel tank area for any
signs of fuel leakage. Continue fueling if no leaks or
other problems are detected.
7.
Allow space at the top of the tank for thermal expansion.
8.
If fuel cannot be pumped in at a reasonable rate, check
for fuel vent blockage or kink in the line.
After Fueling
1.
Replace the fuel fill plate and wipe up any fuel spillage.
Discard any rags that you may have used to wipe up
fuel spillage in a safe place.
2.
Open the engine compartment and all hatches, win-
dows, doors and other compartments that were closed
during fueling. Inspect these areas for the odor of fuel
vapors and visible fuel leakage. Any sign of fuel leak-
age or any indication of vapors must be investigated
and corrected before starting the engine.
3.
Run the bilge blower for at least five (5) minutes before
starting the engine. Continue to run the bilge blower until
the boat is underway and has reached its cruising speed.

AY
Instrumentation
A full set of instruments, installed on your Larson boat,
show what is taking place within your engine. Consult with
your Larson dealer about the normal readings of the
gauges upon delivery of your boat. This will provide you
with a reference point for the life of the engine. Keep in
mind some gauges tend to fluctuate which is not uncom-
mon. But when operating your boat, investigate all gauges
that show a greater or less than normal reading.
NOTE:Some brands of engines are equipped with multi-
function gauges and alarms. See engine owner’s manual
for additional information.
Fuel Gauge
Displays the amount of fuel contained within the fuel
tank(s). The most accurate reading of the fuel gauge is at
idle speed when your boat maintains an approximately
level position. Underway, the fuel gauge will usually indi-
cate a higher fuel level than is actually in the tank due to
the bow of the boat being higher than at rest. Since gauge
readings are approximate, they should be compared to the
hours of use versus known fuel consumption, or gallons
per hour (GPH). The most common practice of good fuel
management is the one-third rule. Y
ou use one-third of
your total fuel on board to travel to your destination and
one-third in returning. The remaining one-third in the fuel
tank should be reserved for emergencies.
Oil Pressure Gauge
The oil pressure gauge will reflect most, if not all, serious
problems that may occur within your engine. A pre-set
valve in the oil pump controls the maximum oil pressure. If
a complete loss of oil pressure occurs, stop the engine
immediately. Serious damage to the engine can result
after loss of oil pressure if the engine continues to run.
Check the engine oil level and fill if low. If oil level is full
and gauge reading is low, contact your Larson dealer or a
qualified mechanic to rectify the problem. Do not restart
the engine until correcting the problem. See engine
manufacturer’s specifications for correct pressure ranges.
Tachometer
Displays the number of revolutions per minute (RPM) that
the engine is running. The gauge displays increments of
100. The tachometer will show the RPMs necessary under
3.8
