SHIFT INTERRUPT
SWITCH
The shift interrupt switch is in contact with the shift
lever (positioned at the base of the powerhead).
The switch is normally open and activates
momentarily as the shift linkage moves.
Excessive shift loads activate the switch. Typically
the switch is depressed when the linkage moves
from the FORWARD or REVERSE position into
the NEUTRAL position.
A depressed switch completes a ground circuit
connected to the EMM. The EMM then shuts off
fuel and spark to three cylinders for approximately
one second to reduce drivetrain loads and ease
shifting, then immediately restores normal engine
operation.
The shift interrupt switch must be released to its
normal open position before the interrupt function
can be activated again. This circuit is not func-
tional above 2500 RPM.
GEARCASE REMOVAL
AND INSTALLATION
Gearcase Removal
Remove pin and washer from shift rod lever to
release the lower shift rod.
Note where the index mark on the gearcase aligns
with the index number of the adjustable trim tab so
the trim tab can be installed in the same position.
Remove the trim tab retaining screw, gasket and
trim tab from the gearcase.
