the tool. Mark the flywheel directly across from the
pointer. Label this mark “A.”
Rotate the flywheel clockwise until the piston
contacts the tool. Mark the flywheel directly across
from the pointer. Label this mark “B.” Rotate fly-
wheel
counterclockwise slightly to release tool
then remove it from spark plug hole.
Use a flexible measuring device, such as a piece
of string, to find the exact center between marks
“A” and “B.” Measure along the edge of the fly-
wheel. Mark and label the center point “C.”
If mark “C” and the cast-in TDC boss on flywheel
are in alignment, the timing pointer is in the cor-
rect location.
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.
Repeat the entire adjustment process to make
sure pointer is aligned correctly.
Install spark plugs. Refer to Spark Plug Indexing
on p. 43.
Timing Verification
Use Evinrude Diagnostics software to synchronize
the mechanical timing of the outboard with the
electronic timing of the
EMM .
Start the outboard.
Use the Settings/Ignition Timing screen of the
diagnostics software and follow the on-screen
instructions.
Check ignition timing after any of the following
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 temperature
before making any timing adjustments.
