FILLING FUEL
1) Put the outboard in the tilt-down
position. Remove the fuel tank cap.
2) Use a funnel if the nozzle on the fuel
can or pump is not small enough or
long enough to fit into the mouth of
the fuel tank.
3) Fill the fuel tank carefully.
4) Close the cap securely after refuel-
ing. Wipe up any spilled fuel.
Ring Free Fuel Additive
Gasoline is a precise blend of many dif-
ferent 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 oxy-
genates has increased. These additives
are important for the engines in passen-
ger cars, but they can have detrimental
effects in marine engines, particularly 2-
cycle outboards because of increased
deposits in the combustion chamber.
When enough deposits collect, piston
rings begin sticking. Performance drops
and engine wear increases dramatically.
