If the pointer alignment is NOT correct, rotate the
flywheel
clockwise to align the mark “C” with the
pointer. Hold the flywheel in this position. Loosen
the pointer retaining screw and adjust the pointer
location to align with the cast-in TDC boss on the
flywheel. Tighten retaining screw.
Install spark plugs. Refer to Spark Plug Indexing
on p. 144.
Timing Verification
Use the
Evinrude
Diagnostics Software program
to synchronize the mechanical timing of the out-
board with the electronic timing control function of
the
EMM
.
Perform timing verification after any of the follow-
ing procedures:
•
Powerhead replacement
•
Crankshaft replacement
•
Flywheel removal or replacement
•
CPS replacement
•
EMM
replacement
•
EMM
software replacement (reprogramming)
IMPORTANT:
Make sure the timing pointer is
set and the outboard reaches operating tempera-
ture before timing verification is performed.
TPS Calibration
Use the
Evinrude
Diagnostics Software program
to tell the
EMM
what the throttle position sensor
voltage level is when the throttle plates begin to
open.
Remove the air silencer.
On the
Settings
screen of the diagnostic software,
click the “Set TPS Calibration” button.
While holding the throttle plates closed, advance
the throttle linkage until it stops. The “Measured
