Fuel and Oil Spills
Regulations prohibit discharging fuel or oily waste
in navigable waters. Discharge is defined as any
action which causes a film, sheen or discoloration
on the water surface, or causes a sludge or emulsion
beneath the water surface. A common violation is
bilge discharge. Use rags or sponges to soak up fuel
or oily waste, then dispose of properly ashore. If a
large quantity of fuel or oil is in the bilge, contact
a Boston Whaler dealer to remove it. Never pump
contaminated bilge discharge overboard.
Fuel System
The fuel system (see Figure 3.7.1) is designed to
meet EPA regulations using certified components
to limit fuel vapor emissions. The fuel system
provides the following benefits:
• Automotive style refueling, nozzle shut-off,
fuel nozzle retention. System sends a signal to
the pump to shut off before there is any spit-
back or well-back through the fill opening.
• Overfill protection reduces the possibility of
accidental fuel spills.
• Reduced hydrocarbon emissions via a
permanently attached cap with a positive
closure mechanism that features an audible
click, to inform when it is sealed.
Fuel Tank
The fuel tank (see Figure 3.7.1) has a usable fuel
capacity of 160 gallons (606 liters). Review and
• Leaking fuel is a fire and explosion hazard;
inspect system regularly. Examine fuel tanks
and exposed lines for leaks and corrosion.
• Fuel spills can be dangerous and can subject
offenders to severe penalties.

CAUTION
!
CAUTION
Use of improper fuel can seriously damage
engine and voids the warranty. Follow engine
manufacturer’s recommendations regarding
the types of fuel and oil to use.
Fuel system on this vessel complies with all
applicable ABYC standards. Fueling station
pump flow rates exceeding 18 gallons (68 liters)
per minute may damage system components
and cause fuel leakage into the vessel.
!
WARNING
understand all fuel related information and warnings
in the owner’s packet and the included safety inserts.
The engine can stall due to fuel starvation or by
allowing sediment to enter the fuel line. Monitor
fuel level often.
Fuel Vent
The fuel tank vent is integrated into the fuel fill deck
fitting. The VaporTec fuel pressure management
system (fuel fill deck fitting, integrated check valve,
fill limit vent valve, and grade valve) ensures that
the fuel system maintains proper vapor pressure,
which, if unchecked, can seriously damage a boat or
engine. The vent serves as an over pressure/vacuum
release with anti-surge and flame/spark arresting
protection. Grade valves have been added to the tank
to allow proper ventilation when the boat is stored, or
trailered, on a moderate incline, without fuel seepage.
Fuel Distribution System
Fuel is delivered to the engine through the fuel
valve, anti-siphon valve (ASV) and the fuel line.
The fuel valve prevents built up tank pressure from
being transferred to the engine while still allowing
fuel to flow. The anti-siphon valve is a safety feature
designed to prevent fuel from siphoning out of the
tank if the fuel line were to be cut or broken below
the level of the fuel in the tank.
Filling the Tank
The fuel system is designed to automatically shut off
the fuel nozzle when the tank is full. The SecureStop
automatic fuel shut off system (fuel fill deck fitting,
integrated check valve, fill limit vent valve), ensures
a clean a trouble-free fill-up. Attempting to fill the
tank past this point may cause some components to
malfunction.
