6.3 Fuel System
Due to the nature of the hull design, your World Cat is equipped with a port and starboard fuel system.
These systems act independently, providing fuel to the engine on their respective side. Tanks are
constructed of polyethylene material to prevent corrosion.
All hoses are NMMA certified, with all fittings clamped securely against leaks. However, a comprehensive
check of all hoses and fittings should be completed at least annually, including those normally hidden from
view. Tighten all connections, and replace deteriorated hoses, clamps, or fittings. The fuel / water separators
should also be replaced in accordance with the Yamaha owner’s manual maintenance schedule, or at least
annually. World Cat has provided inspection access through removable inspection ports in the cockpit sole,
in the cockpit liner below the fuel fills, and in the port and starboard mechanical rooms.
The fuel / water separators are located in the port and starboard aft mechanical rooms. Inspect these
filters regularly, and replace when needed, or in accordance with the Yamaha owner’s manual maintenance
schedule. World Cat recommends that every boat carry a spare filter onboard for each motor. When
purchasing fuel from remote or unfamiliar sources, special attention should be paid to the condition of the
fuel / water separators.
6.3.1 Fuel System Benefits
• Automotive-style refueling
• Automotive Nozzle shut-off – system sends signal to the pump nozzle to shut off before there is any
spit-back through the fill opening
• Fuel nozzle retention
• Overfill protection – reduces the possibility of accidental fuel spills
• Reduces hydrocarbon emission through the use of specially designed fuel fill. The fuel fill has a
permanently attached cap incorporating a positive closure mechanism with an audible click, to let
you know when the cap is sealed.
6.3.2 Fuel Tank
Your boat is equipped with two low permeation crosslink Polyethylene fuel tanks with a usable fuel capacity
of 110 gallons per tank. The usable capacity of the fuel tank is different from the tank capacity marked on
the tank from the manufacturer. The difference is the non-usable portion of the tank which results from
the fuel in the tank that is below the pickup tube and the ullage area that has been incorporated into your
tank. It is recommended that you follow all the instructions regarding the filling of fuel tanks. Fuel tanks with
levels less than ¼ full can cause engine stalling problems due to fuel starvation or by allowing sediment and
dirt to enter the fuel supply lines. Keep the tank full and monitor the fuel level often to prevent this from
happening.
6.3.3 Fuel Vent
The fuel tank vent is integrated into the fuel fill deck fitting (See fig. 6.3.6) The vent serves as an over
pressure / vacuum release with anti-surge and flame / spark arresting protection. The fuel vent system also
plays an important role in controlling the “FULL” level of fuel with the use of FLVV (Fill Limit Vent Valve).
Grade Valves have been added to the tank which allows proper ventilation of the tank when the boat is
stored, or trailered, on a moderate incline, without fuel. Always inspect to insure that the fuel fill deck fitting
is free of debris and in proper working condition.
