The fuel sender is equipped with a float that moves up and down with the fuel level in the tank. The fuel
level information is sent to the fuel gauge and keeps you informed of the approximate fuel level in the
tank. If you feel that your fuel gauge is reading incorrectly, before considering changing the gauge, have
your Pro-Line dealer’s Service Department or a qualified service professional remove the fuel sender and
check to make sure that the float is able to move up and down freely.
Fuel Water Separators
Depending on your selection of the various optional engine packages, your boat may be equipped with a
fuel water separator for each engine. However, some engines come equipped with a built in fuel water
separator. Please refer to the owner’s manual provided by the manufacturer of your engine package for
operational procedures and for information related to the care and maintenance of their product. When in
doubt, always defer to the engine manufacturer’s instructions and/or recommendations.
If your engine package requires the installation of fuel water separators, they will be mounted in the bilge
on the inside of the port and starboard stringers. There is one unit for each motor. The “spin on” filter
cartridges should be renewed every season at a minimum. Fuel tanks that are not kept full accumulate
water faster due to condensation. Therefore, the filter cartridges may need to be replaced more often
depending upon usage and conditions or if motors begin to run rough. If water should somehow enter
your fuel tank via condensation, your fuel source, etc., it will become trapped in the fuel water separator
before it is able to travel through the fuel system and to your engine. When replacing the filter cartridges
for the fuel water separators, coat the rubber seal with a film of grease or oil to help prevent sticking.
Please refer to the owner’s manual provided by your engine manufacturer for proper procedures. Some
engines will not have a separate fuel water separator located in the bilge. Instead it/they will be located
on the engine itself. Check engine specs.
If you have selected the optional air conditioner system, a designated fuel water separator will be installed
on the inside of the port stringer specifically for this optional installation.
Primer Bulbs
Depending on your selection of the various optional engine packages, your boat may be equipped with
primer bulbs. If required, a primer bulb will be installed for each engine. Primer bulbs are used to prime
the fuel pump in the motor with fuel. Squeeze the primer bulb a few times until resistance is felt. If no
resistance develops and the fuel pump will not prime, you may be out of fuel, the primer bulb may be
defective, or a leak may have developed allowing air into the system. The primer bulbs (if applicable) are
located with the rigging tubes where they exit the bilge and are easy to get to by standing on the dive
platform.
Note: Not all engines require primer bulbs. Refer to the engine manual for verification.
Oil Tank and Oil Fill
Depending on your selection of the various optional engine packages (i.e.,
oil injected outboard engines), your boat may be equipped with remote oil
tanks. If your engine package requires the installation of an oil tank, it will
be mounted in the bilge beneath the transom sink and can be accessed by
removing the battery switch panel. The oil fill will be installed on the port
gunwale in close proximity to the transom sink.
Make sure that the oil tanks are well stocked with the type of engine oil that
is recommended by your engine manufacturer for your engines; refer to
your engine manual. It is imperative that the oil supply remains clean and
uncontaminated by water or dirt. Check to make sure the oil lines are free
from leaks, kinks and chafing. Some motors use a primer bulb to initiate oil
flow. Air may periodically enter the system and require purging. Refer to
your engine manual for specific instructions.
