OIL AND FUEL
FUEL SYSTEM INFORMATION
In the United States, the U.S. EPA requires
"low permeability" fuel hose, fuel primer
bulbs, portable fuel tanks and fuel caps to be
used with outboard engines.
IMPORTANT: Fuel distribution hoses in the
boat must deliver fuel at a specific flow rate.
Minimum inside diameter of fuel hoses must
be 5/16 in. (7.9 mm).
Fuel systems with built-in tanks, particularly
those that include antisiphon valves and filter/
primer units, may have restrictions not allow-
ing the engine fuel pump to deliver sufficient
fuel under all conditions. This can result in a
loss of performance. If a performance prob-
lem exists, see your Dealer.
Fuel Filters
A boat-mounted water-separating fuel filter
assembly will help prevent water and other
contaminants from entering the engine fuel
system.
Use of a boat mounted water-separating fuel
filter is highly recommended on all boats.
Boat-mounted water-separating fuel filter as-
semblies must meet the required fuel flow and
filter specification. Refer to Boat-Mounted
Fuel Filters on page 66.
Fuel Connector
If equipped, disconnect fuel hose connectors
from the engine’s fuel connector when the en-
gine is not in use.
Fuel System Priming
If the outboard is run out of fuel, refill the fuel
tank and squeeze the primer bulb until firm.
Rope Start Models
Prime the electric fuel pump by first removing
the engine cut–off switch clip and then pulling
the rope at least two times. This will cause the
fuel pump to fill the injectors. Replace the en-
gine cut–off switch clip and follow the normal
starting procedure.
A WARNING
If engine is equipped with a quick-dis-
connect fuel hose, you MUST disconnect
the fuel hose from the engine and the
fuel tank to prevent fuel leaks:
• Whenever the engine is NOT being
used
• Whenever the engine is being trailered
• Whenever the engine is in storage
A small amount of fuel may be released
when the fuel connector is disconnected.
Always wipe off any fuel spillage.
Store portable fuel tanks in well-venti-
lated areas, away from heat sources and
open flames. Close the vent screw of the
fuel tank cap, if equipped, to prevent
escape of fuel or fuel vapors which could
accidentally ignite. Do not allow discon-
nected fuel hoses to leak fuel.
