Specifications and Requirements
•
Avoid getting water and contaminants in
the fuel tank. Contaminated fuel can
cause
poor performance or engine damage. Use
only fresh gasoline that has
been stored in
clean containers.
Gasohol
There are two types of gasohol: gasohol
containing ethanol (E10) and that containing
methanol. Ethanol can be used if the ethanol
content does not exceed 10% and the fuel
meets the minimum octane ratings. E85 is a
fuel containing 85% ethanol and must not be
used in your outboard motor. All ethanol
blends containing more than 10% ethanol can
cause fuel system damage or cause engine
starting and running problems. We do not
recommend gasohol containing methanol
because it can cause fuel system damage or
engine performance problems.
It is recommended that you install a water-
separating marine fuel filter assembly (10
micron minimum) between your boat's fuel tank
and outboard motor when using ethanol.
Ethanol is known to allow moisture to be
absorbed into boat fuel tanks and systems.
Moisture in the fuel can cause corrosion of
metallic fuel system components, starting and
running complaints and require additional fuel
system maintenance.
Ring Free Fuel Additive
Gasoline is a precise blend of many different
substances, each chosen to give certain
characteristics. Gasoline blends have been
changing in recent years in response to
concerns about pollution and resulting
emissions
regulations. One of the most obvious
changes
has been the elimination of lead from
most fuels.
As gasoline has changed, the amount of additives
such as aromatics and oxygenates has
increased. These additives are important for
the
engines in passenger cars, but they can
have
detrimental effects in marine engines, because of
increased deposits in the combustion chamber.
When enough deposits collect, piston rings begin
sticking. Performance
drops and engine wear
increases dramatically.
While many additives available may reduce
deposits, we recommend the use of
Ring Free
Fuel Additive. It has repeatedly proven its ability to
clean combustion deposits from inside the engine,
notably the critical piston-ring-land area, and fuel
system components. Follow product labeling
for
use instructions.
Anti-fouling paint
A clean hull improves boat performance. The
boat bottom should be kept as clean of marine
growth as possible. If necessary, the boat bottom
can be coated with an anti-fouling paint
approved for your area to inhibit marine
growth.
Do not use anti-fouling paint which includes
copper or graphite. These paints can cause
more rapid engine corrosion.
Motor disposal requirements
Never illegally discard (dump) the motor.
Emergency equipment
Keep the following items onboard in case
there is
trouble with the motor.
•
A tool kit with assorted screwdrivers, pliers,
wrenches (including metric sizes), and
electrical
tape.
