OUTBOARD WILL NOT SHUT OFF
OBSERVATION
Outboard starts and
runs, normal
performance while
running
OUTBOARD STARTS AND STALLS
OBSERVATION
Outboard may not run
for more than a few
seconds
T–4
POSSIBLE CAUSE
Key switch or wire harness
ground
Stop circuit wiring
EMM failure
POSSIBLE CAUSE
Faulty wiring, connections, or
grounds
Incorrect, fouled, or worn spark
plugs
Low or no alternator output
(55 V)
Capacitor or 55 V circuit wiring
Contaminated or poor fuel
quality
Low fuel pressure
Air in fuel system
Fuel supply restricted
Injector electrical circuit or
control function
Restricted or leaking fuel
injector(s)
EMM program, timing, or
operation
Weak or erratic ignition output
Internal powerhead damage
PROCEDURE
Check key switch and ground to key switch, refer
to SYSTEM ANALYSIS on p. 113 and
ELECTRICAL AND IGNITION on p. 135
Check EMM LED indicators. Check wire harness
(black/yellow) and key/stop switch(s).
Check EMM LED indicators and eliminate stop
circuit as possible cause. Stop wire (black/yellow)
has 4.0 VDC from EMM with key on or outboard
running.
PROCEDURE
Check all grounds, connections, and wiring
Replace spark plugs
Check voltage on 55 V circuits, refer to SYSTEM
ANALYSIS on p. 113 and ELECTRICAL AND
IGNITION on p. 135
Check capacitor and 55 V circuit, refer to
SYSTEM ANALYSIS on p. 113 and
ELECTRICAL AND IGNITION on p. 135
Check or replace fuel supply
Check pressure, refer to FUEL SYSTEM on
p. 173
Check for air in fuel supply manifold, refer to
FUEL SYSTEM on p. 173 (vapor separator
venting and fuel supply)
Check primer bulb, anti-siphon valve, and fuel
pick-up, check for fuel system air leaks
Check voltage at injectors, refer to SYSTEM
ANALYSIS on p. 113
Check injectors, refer to FUEL SYSTEM on p. 173
Check EMM program and timing; check injector
coefficients; and monitor injector control wires and
ignition primary outputs
Check ignition, refer to SYSTEM ANALYSIS on
p. 113 and ELECTRICAL AND IGNITION on
p. 135
Check and repair as needed
