Section 3 • Using Your Boat contains important fueling information. Take time to read all the fuel related information in the owner’s manual.

The 275 Performance standard gasoline fuel system consists of a 90 gallon fuel tank, fuel tank vent, an anti-siphon valve, engine fuel supply line and fuel fill (See Figure 5.1.1).

The fuel tank vent serves as a pressure/vacuum release and safety overflow. The fuel vent is located inside the fuel cap on the port side of the hull. Periodically check the vent to assure that it is not clogged.

!CAUTION

Never start an engine until you are certain that fuel fumes are not present in engine compartment or elsewhere in the boat.

Anti-Siphon Valve (Inboard/Outboard Engine Only)

The fuel pick-up at the fuel tank has an anti-siphon valve to prevent fuel from siphoning out in the event of line failure (See Figure 5.1.1 and 5.1.2). In an emergency situation, remove the anti-siphon valve if the engine is not getting fuel. NOTE: Replace with new anti-siphon valve or fuel shut off valve as soon as possible as anti-siphon protection is required by federal law.
