engines will consume from the selected fuel
tank only.
Fuel Tanks
The fuel pick-up tubes are positioned in the
tanks to achieve optimum fuel usage, fuel
line routing, etc. At certain speeds and hull
trim angles, the fuel supply at the withdrawal
tube can increase or decrease accordingly.
Be extremely careful when attempting to
operate the boat when low on fuel. Though
some fuel may be in the tank, the trim angle
of the boat may cause the fuel to flow away
from the pickup tubes.
Fuel Gauge Senders
The fuel gauge senders are more accurate
when the boat is stationary and level.
Because of the change in attitude when the
boat is underway, variations in gauge read-
ings can occur. This system is a relative indi-
cation of the available fuel supply and not a
calibrated instrument.
Fuel Fills
A fuel fill is located on each gunwale and is
marked “GAS.” The fuel fill is opened by
turning it counterclockwise. After fueling,
screw the cap on in a clockwise direction
until an audible click is heard indicating that
the cap is seated. If the cap is lost or dam-
aged replace only with original equipment.
During refueling the tank vents out at both
the fuel fill plate and the vent located on the
side of the hull. Note: There should not be
any residual fuel at the vent but there could
be residual fuel at the deck fill plate. Do not
block or restrict either of these vents.
Fill the fuel tank slowly and monitor the fuel
gauge while filling. Once fueling is com-
pleted wash the areas around the fuel fill(s)
to help reduce discoloration of the fiberglass
or striping. Use only the fuel recommended
by the outboard manufacturer; refer to the
engine owner’s manual for additional infor-
mation.
If fuel is added to any other tank, DO NOT
attempt to pump fuel out; these systems are
not designed to pump fuel. Fuel must be
removed by qualified personal only. Fuel in
other systems will also require replacement
of that system and/or many components.
EPA Fuel Fill
Fuel Filters
Fuel Filters
Fuel filters are located in the machinery
space. The filters are the water separator
type and there is one filter for each engine
fuel line. Check both filters for water fre-
quently to ensure an adequate supply of
clean, dry fuel to the engines. The filter ele-
ments should be changed once a season.
Turn off all electrical switches before servic-
ing the fuel system and DO NOT drain any
fuel into the bilge. Prime fuel system and
check all fittings for leaks before starting the
engines. Check all fuel lines and fittings for
leaks before and after starting the engines
and after any fuel system service.
