FLYWHEEL AND STATOR
SERVICING
IMPORTANT: Weak flywheel magnets can
cause low alternator output and affect outboard
performance. Weak flywheel magnets can also
cause low readings on ignition test equipment,
such as a peak-reading voltmeter, which might
cause unnecessary parts replacement.
An accurate test of alternator output can help
determine the flywheel’s condition. Refer to
CHARGING SYSTEM TESTS on p. 137.
Flywheel Removal
Remove the EMM. Refer to EMM SERVICING on
p. 110.
Disconnect the vapor separator vent hose, crank-
shaft position sensor, throttle position sensor, air
temperature sensor, and oil pump electrical con-
nectors.
Disconnect the stator connector, two port side trim
system connectors, port engine temperature sen-
sor, and the port ground terminal.
Remove the four screws holding the electrical har-
ness base.
Lift the electrical harness base out of the way.
Use Flywheel Holder, P/N 771311, or equivalent,
and a socket to remove the five flywheel retaining
nuts and washers. Discard flywheel nuts.
Install bushing from Flywheel Puller Adaptor Kit,
P/N 5007181, on top of crankshaft. Place puller
from Flywheel Service Kit, P/N 434649, over
bushing.
WARNING
To prevent accidental starting while ser-
vicing, disconnect battery cables at the
battery.
