Wide Open Throttle Adjustment
Adjust wide open throttle (WOT) stop screw until
the tip protrudes 0.25 in. (8 mm) through the throt-
tle lever.
Open throttle to WOT position and make sure the
throttle shaft pin is vertical. If adjustment is
required, turn the cam screw in to open the throttle
valve and out to close the throttle valve.
Maximum Spark Advance
No maximum spark advance adjustment is neces-
sary. Correct ignition primary lead position is all
that is required to maintain proper ignition timing.
Orange/blue lead must connect to top ignition coil.
Idle Speed
The boat must be in the water, under normal oper-
ating conditions, with correct propeller installed.
The boat’s movement must be unrestrained. The
boat must not be tied to a dock or trailer.
Before proceeding with this procedure, be sure
the low speed needle is properly adjusted. Refer
to CARBURETOR MIXTURE ADJUSTMENT on
p. 114.
Turn the idle speed knob fully counterclockwise to
the full SLOW position (tiller models).
Start the outboard and allow it to reach normal
operating temperature. When speed is reduced,
engine must idle at 700 ± 25 RPM in FORWARD
gear. Stop the outboard and adjust the idle speed
screw to change idle speed.
