Fuel System
several minutes while the fuel system is primed
so the engines can be restarted. This could en-
danger the boat and crew in rough seas, an inlet
or a busy waterway. Always make sure to return
the selector valves to the main position when you
fill the tank.
NOTICE:
The procedure to prime the fuel system on
outboard engines is specific to the type and
model of engines on your boat. You should
refer to engine manufacturer owner’s manual
for the priming procedure for your engines.
3.3 Diesel Generator Fuel System
The diesel fuel system for the generator is com-
pletely separate from the gas system. The diesel
fuel tank is located in the bilge below the starboard
side of the cockpit and is filled from a fuel fill deck
plate on the starboard gunnel labeled “Diesel.”
The diesel fuel system is not equipped with an
anti-siphon valve and there is a fuel return line
for the engine that returns unused fuel to the fuel
tank. A separate fuel pump mounted near the
diesel fuel filter in the aft systems station supplies
fuel from the tank to the generator.
Proper diesel engine operation requires a good
supply of clean, dry diesel fuel. Improper ma-
rina fuel storage techniques, limited boat usage,
etc. can cause the fuel to become contaminated.
Periodically, it may be necessary to pump accu-
mulating water and contaminated fuel from the
bottom of the fuel tank. If the generator fuel
system on your boat becomes contaminated,
contact your dealer or Scout Customer Service
for assistance.
Algae can grow in the accumulated water in die-
sel fuel tanks. This condition is most prevalent in
warm climates. Periodically adding a high quality
diesel fuel additive containing an algicide may be
required to control algae in your boating area.
You should contact your dealer or the generator
manufacturer for additional information regarding
fuels and additives.
NOTICE:
Do not allow the generator to sit unused
for an extended period with the fuel tank
less than full. Changes in temperature and
weather conditions can cause condensation
in diesel fuel tanks that are less than 3/4
full.
Diesel Fuel Filter
The diesel fuel filter is installed near the generator
in the port side of the aft systems station. Check
the primary filter for water periodically and replace
the filter cartridge as needed.
Water is drained from the primary filter by plac -
ing a cup under the filter and draining through
the petcock at the bottom of the filter until clean
fuel flows. It is particularly important to monitor
the condition of the fuel filter frequently because
diesel engines circulate much more fuel than they
consume. Because of the volume of fuel that flows
through the filter, the element must be changed at
least twice a season or more frequently depending
on the quality of the fuel and the hours run. Follow
the filter or generator manufacturer’s instructions
for cleaning and replacing the filter element.
NOTICE:
Diesel fuel systems may need to be primed
after servicing. Refer to the generator
owner’s manual for information on priming
the fuel system.
