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 Evinrude Diagnostics software to verify and
adjust timing. Refer to the software's help system
for outboard timing verification procedures.
WARNING
To prevent accidental starting while servic-
ing, disconnect the battery cables at the
battery. Twist and remove all spark plug
leads.
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.

1. Piston stop tool
Rotate flywheel counterclockwise until the num-
ber 1 piston contacts the tool. Keep pressure on
the flywheel to position the piston firmly against
142
the tool. Mark the flywheel directly across from the
pointer. Label this mark "A."
1
1. Timing pointer
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 to find the exact
center between marks "A" and "B." Measure along
the edge of the flywheel. Mark and label the cen-
ter point "C." If mark "C" and the cast-in TDC boss
on flywheel are in alignment, the timing pointer is
in the correct 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.
