Section 3 Fuel Systems
General Description
Read and understand all the fuel-related information
and warnings in this section and in your outboard
engine operator’s manual.
Your boat is equipped with a built-in gasoline fuel sys-
tem. The fuel system includes a single, centerline fuel
tank. The fuel tank is manufactured from marine-
grade 5052-H32 aluminum alloy and it is installed in
the mid-bilge area. The fuel tank has a manufacturer’s
compliance label next to the fuel level sending unit.
The compliance label includes information about tank
capacity, construction materials, and date of manufac-
ture.
Your fuel system is designed to meet the diurnal emis-
sions requirements outlined in ABYC Standard
H24.18.4.1 and in Code of Federal Regulations (CFR)
Title 40, sub-parts 1045 and 1060. These design ele-
ments work to limit liquid and hydrocarbon emissions
from your on-board gasoline fuel system.
The fuel tank working capacity is 150 gallons (568
liters).
The fuel tank has an electric sending unit that sends
fuel level readings to the fuel gauge at the helm sta-
tion.
The fuel tank has a separate fuel withdrawal tube for
each outboard engine. Each fuel withdrawal tube has
a manual fuel shutoff valve. You can use these valves
to stop fuel flow during storage, during fuel system
servicing, or in the event of an on-board fire.
The fuel valve is in the ON position when the lever is
parallel with the valve body and the fuel valve is in the
OFF position when the lever is perpendicular to the
valve body.
The Fuel System Diagram in this section shows loca-
tions of the fuel tank, fuel fill, fuel tank vent, fuel level
sending unit, fuel withdrawal tubes, fuel shutoff valves,
fuel filters, and certain emission system components.
