OUTBOARD STARTS AND STALLS
OBSERVATION POSSIBLE CAUSE PROCEDURE
Outboard starts and
runs, normal
performance while
running
Key switch or wire harness
ground
Check key switch and ground to key switch, refer
to
SYSTEM ANALYSIS and ELECTRICAL AND
IGNITION
Stop circuit wiring
Check EMM LED indicators. Check wire harness
(black/yellow) and key/stop switch(s).
EMM failure
Check EMM LED indicators and eliminate stop
circuit as possible cause. Stop wire (black/yellow)
has 4.0 VDC from

pick-up, check for fuel system air leaks
Injector electrical circuit or
control function Check voltage at injectors, refer to SYSTEM
ANALYSIS

injector(s)
Check injectors, refer to FUEL SYSTEM
EMM program, timing, or
operation
Check EMM program and timing; check injector
coefficients; and monitor injector control wires and
ignition primary outputs
Weak or erratic ignition output
Check ignition, refer to
SYSTEM ANALYSIS
and
ELECTRICAL AND IGNITION
