NOTICE
Use only clean, dry fuel of the type and grade
recom mend ed by the engine manu factur er.
The use of incorrect or contaminated fuel can

warranty. Refer to the section on Gasoline
Requirements in the engine manual for
information on octane specifi cations.
In twin engine applications, the port and starboard fuel
tanks are locat ed for ward and outboard in relationship
to their respective engine. See Figure I1. The capacity

See Figure I2. This fuel valve system allows you to
manually select which fuel tank you want your engines
to draw fuel from. The generator (if applicable) uses a
separate fuel pick-up. Please see Figure I8 at the end
of this section for fuel valve operations.
