GASOLINE FUEL SYSTEM
In this section, a typical EPA approved domestic gasoline
fuel system is introduced.
fuel tank, fuel feed lines, ll and vent ttings along
with fuel lters, emission devices natural and powered
ventilation systems.
Gasoline today is processed in a di erent manner than
it was a few years ago. As a result it has become more
unstable and the product shelf life has been shortened.
As part of the Volvo product features the gasoline engine
EVC system and transmissions are all protected by a
fault handling system should a malfunction develop.
A portion of this fault system is used to monitor the
gasoline fuel system. Mercruiser propulsion systems
o er "Smartcra " technology which delivers key engine
functions.
Select codes warn the captain with a "buzzer" sound
while others will display on the helm tachometer, display,
or alarm panel. e "pop-up" will alternate between
the cause of the fault and a task to perform to aid in
eliminating the situation.
It is important to read and understand your Volvo or
MercCruiser propulsion owner's manual in order to
react to a fault code should a malfunction display on the
instrumentation or an alarm sound.
Note that outboards utilize the same style fuel tank as the
stern drive models with slight di erences in the fuel system
components.
For example a special bulb and hose is supplied by the
engine manufacturer to feed the fuel from the tank to the
outboard engine. Read and understand the outboard
owner's manual fuel section and safety information before
attempting to use the vessel.
On outboard models due to a possible re or explosion
danger never store ammable liquids and/or portable
outboard fuel tanks in any onboard storage compartment

GASOLINE SPECIFICATIONS/OCTANE RATINGS
Gasoline Requirements- Use regular non-leaded gaso-
line with the following minimum octane rating for
stern drive engines:
• Inside United States-(R+M)2 (AK)- 87
• Outside United States- (RON) -90
e 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 Regal boat may be oper-
ated with gasoline blended with no more than 10% eth-
anol and that meets the minimum octane speci cation.
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% eth-
anol. A loss of performance may occur and the engine
will not be covered by the engine manufacturer's war-
ranty.
Outboard models depending on the model may require
a mid-range octane level verses a lower regular octane
level. Refer to your outboard manufacturer's operation
manual for correct information regarding the proper
octane level for your outboard model. Using the wrong
octane level may cause permanent engine damage. such
as piston detonation.
As an option contact your outboard manufacturer's hot
line or text on web with fuel related questions. Also,
contact your closest Regal dealer.
