Gasoline Fuel System
In this section, a typical EPA approved domestic
gasoline fuel system is introduced. The fuel system
includes the fuel tank, fuel feed lines, fill and vent
fittings along with fuel filters, emission devices,
natural and powered ventilation systems.
Gasoline today is processed in a different manner
than it was a few years ago. As a result it has be-
come more unstable and the product shelf life has
been shortened.
Outboards
in this size
range nor-
mally uti-
lize a metal
fuel tank.
A special
low perme-
ability bulb
and hose is
supplied by the engine manufacturer to feed the
fuel from the tank to the outboard engine. Some-
times it is necessary to pump the gas line hose
bulb before starting the engine.
Note that the fuel
line bulb and hose for each engine is in the lazarette
storage area.
If the need arises to replace the fuel
bulb be sure to turn the arrow imprinted on the
bulb toward the engine side for correct fuel flow.
Read and understand the outboard owner’s man-
ual fuel section and safety information before at-
tempting to use the vessel.
Note that due to a possible fire or explosion danger
never store flammable liquids and/or portable out-
board fuel tanks in any onboard storage compart-
ment such as the cockpit Lazarette locker.
Gasoline Specifications/Octane Ratings:
Gasoline Requirements- Use premium non-leaded
gasoline with the following minimum octane rating
for Yamaha outboard engines:
• Minimum pump octane number (PON) is 89
.
The use of leaded fuels will damage the catalysts
and can not be used with catalytic converters.
Gasoline in the United States and other areas is
blended with 10% ethanol and is known as E-10
at the pumps. Marine engines used in your Re-
gal boat may be operated with premium unleaded
gasoline blended with no more than 10% ethanol
and that meets the minimum octane specification.
Do not use ethanol blends greater than 10% such
as a newer blend for select motor vehicles called
E-15. Your marine engine may be damaged by
more than 10% ethanol. A loss of performance
may occur and the engine will not be covered by
the engine manufacturer’s warranty.
Refer to your outboard manufacturer’s operation
manual for additional information regarding the
proper octane level for your outboard model. Us-
ing the wrong octane level may cause permanent
engine damage such as piston detonation.
As an option contact your outboard manufacturer’s
hot line or surf the web with fuel related questions.
Also, additional fuel system information may be as
close as your Regal dealer. Your Regal dealer has
special training on the propulsion and Regal vessel
systems.
