Fuel System Priming

Fuel System Priming
Priming the Fuel System
WARNING
Fuel vapors are highly flammable. Perform
the following procedure in a well ventilated
area. Extinguish all smoking materials and
make certain no ignition sources are present.
Failure to check for fuel leaks could allow a
leak to go undetected, resulting in fire or
explosion and may cause personal injury or
property damage.
NOTICE
A fuel primer bulb is NOT required and
should NOT be installed on Evinrude E-TEC
G2 models.
Evinrude E-TEC G2 models are equipped with an
electric fuel lift pump. The electric fuel lift pump
runs continuously up to 1 minute when the vapor
separator low fuel switch is active.
Make sure the battery is fully charged and reads a
minimum of 12 VDC. Turn the Master Power / Key
Switch to the ON position to start the fuel priming
process.
The high-pressure fuel circuits and injectors will
prime as the outboard is cranked with the starter.
Observe all fuel lines, both in the boat and on the
outboard. Repair any fuel leaks.

Fuel System Tests

WARNING
Use caution when working on any pressur-
ized fuel system. Wear safety glasses and
work in a well ventilated area. Extinguish all
smoking materials and make certain no open
flames or ignition sources exist. Before start-
ing any fuel system service, carefully relieve
fuel system pressure. Failure to properly
relieve fuel system pressure can result in
spraying fuel and/or excessive fuel spilling
during servicing. Fuel is flammable and can
be explosive under certain conditions.

Fuel System Pressure Tests

WARNING
Protect against hazardous fuel spray. Before
starting any fuel system service, carefully
relieve fuel system pressure.
Relieve fuel system pressure. See Relieving Fuel
System Pressure on p. 168.
Check the Evinrude
Occurred Faults screen for current fault codes
before troubleshooting. Correct any problems and
clear the codes FIRST.
Inspect all fuel hoses, filters, and connections.
Check quality of fuel supply.
Use shop towels to clean up any spilled fuel.
ENVIRONMENTAL NOTE
Dispose of fuel contaminated towels in an envi-
ronmentally responsible manner, or according to
local regulations.
Running Fuel System Tests
Run or crank the outboard.
Use the Evinrude Diagnostics software Monitor
screen to check system voltage. If voltage is low,
or drops as RPM increases, refer to Stator Volt-
age Output Test on p. 125.
Use an inductive timing light to monitor the injec-
tor control wire (connector pin 2) for each injector.
