TIMING ADJUSTMENTS
Timing Pointer
The timing pointer must be adjusted to indicate
top dead center (TDC) of the number 1 piston.
This reference to the position of the number 1 pis-
ton is used to synchronize the electronic timing
controlled by the EMM with the mechanical posi-
tion of the number 1 piston.
Use the Evinrude Diagnostics Software program
to verify and adjust timing. Refer to the software’s
help system for outboard timing verification proce-
dures.
IMPORTANT: The pointer on these models has
two indicator points. The point labeled “V4” is
used for 60° V4 models. The unlabeled point is
used for 60° V6 models.
Disconnect the battery cables at the battery.
Remove spark plugs. Rotate the flywheel clock-
wise to 30° ATDC.
Install Piston Stop Tool, P/N 342679, into the
spark plug hole of the number 1 cylinder.
Rotate flywheel counterclockwise until the num-
ber 1 piston contacts the tool. Keep pressure on
the flywheel to position the piston firmly against
the tool. Mark the flywheel directly across from the
pointer. Label this mark “A.”
WARNING
To prevent accidental starting while ser-
vicing, disconnect the battery cables at
the battery. Twist and remove all spark
plug leads.
