Pressure Test
This test requires Injector Test Fitting kit,
P/N 5005844.
Disconnect the battery cables at the battery.
Relieve fuel system pressure. See Relieving Fuel
System Pressure on p. 189.
IMPORTANT: Perform test with injector
mounted to cylinder head and fittings installed
with manifold retainer.
Use cap and tie strap to seal off outlet fitting and
connect a 0 to 30 psi (0 to 207 kPa) pressure
tester to the inlet fitting. Pressurize the injector to
30 psi (207 kPa). Pressure must hold for at least
five minutes.
Static Test
Use the Evinrude Diagnostics Software program
to test circulation pump and fuel injectors.
Refer to FUEL DELIVERY on p. 131 for additional
test procedures.
IMPORTANT: Static tests are performed when
outboard is not running. Listen carefully for fuel
pump and injector activation. These tests are
operating components on battery voltage. The
DANGER
Contact with a rotating propeller is likely
to result in serious injury or death. Assure
the engine and prop area is clear of people
and objects before starting engine or
operating boat. Do not allow anyone near
a propeller, even when the engine is off.
Blades can be sharp and the propeller can
continue to turn even after the engine is
off. Remove propeller before servicing
and when running the outboard on a flush-
ing device.
DO NOT run the engine indoors or without
adequate ventilation or permit exhaust
fumes to accumulate in confined areas.
Engine exhaust contains carbon monox-
ide which, if inhaled, can cause serious
brain damage or death.
WARNING
Use caution when working on any pres-
surized fuel system. Wear safety glasses
and work in a well ventilated area. Extin-
guish all smoking materials and make cer-
tain no open flames or ignition sources
exist. Before starting any fuel system ser-
vice, carefully relieve fuel system pres-
sure. Failure to properly relieve fuel
system pressure can result in spraying
fuel and/or excessive fuel spillage during
servicing. Fuel is flammable and can be
explosive under certain conditions.
