Owner’s Manual Supplement
To test a float switch:
1.
Lift the float up by turning the plastic float
switch insert (where the wires enter the
housing)
1/4
turn counterclockwise. As the
float is lifted, the bilge pump should turn on.
If lifting the float does not turn the pump on,
check the inline fuse. If the fuse is good but
the switch does not work, it may indicate a
bad switch or possibly a low battery.
2.
Release the plastic insert to automatically
lower the float and return the float switch to
auto mode.
Fuel System
Carefully read the fuel section of the Owner’s Manual and
the engine operation manual, paying special attention to
the subject of fuel recommendations. These manuals can
be found in your yacht’s owner’s packet.
Fuel Quality
•
Make sure your fuel suppliers are reputable and can be
relied upon to furnish clean, high quality fuel.
•
Once you have found such suppliers, keep your tanks
as full as possible with their fuel, allowing for expan-
sion due to temperature variations.
•
Then, if you are forced to add to the tank with a poten-
tially poor quality supply, the portion of poor quality
fuel will be minimized.
Fuel Fills and Vents
•
Fuel fill receptacles are located on each side of the aft
deck and are marked either “Diesel” or “GAS”.
•
If you experience difficulty filling a fuel tank, check to
see that the fuel fill and vent lines are free of obstruc-
tions and kinks.

•
It is very important that the fuel system be inspected thoroughly the first time it is filled and
at each subsequent filling.
•
The fueling instructions in the Owner’s Manual and the fuel recommendations in the engine
operation manual must be followed.
WARNI NG!
!
•
Avoid the storage or handling of gear near the fuel lines, fittings and tank.
•
DIESEL: Air in the diesel supply system can stop an engine or severely restrict perfor-
mance. If you suspect air in the fuel lines, refer to your engine operation manual for detailed
instructions on how to bleed the system.
