If you change propellers, be sure to perform the
above check again, to confirm that the engine
speed under full throttle is within the specified
range.

PROPELLER INSTALLATION

 WARNING
Failure to take proper precautions when
installing or removing the propeller can
result in severe personal injury.
When installing or removing the propeller:
• Always shift into "Neutral" and remove
the emergency stop switch lock plate
so that the motor cannot be started
accidentally.
• Wear gloves to protect hands, and
"lock" the propeller by placing a block
of wood between the blades and the
anti-cavitation plate.
To install a propeller on your outboard motor,
use the following procedure:
1. Coat the propeller shaft splines 1 liberally
with Suzuki water resistant grease to help
prevent corrosion.
2. Place the stopper 2 on the shaft.
3. Slide the propeller 3 onto the shaft.
4. Screw on the propeller nut 4 and tighten it.
Align the hole in the propeller nut with the
hole in the shaft, then insert the cotter pin 5
and bend it so that it can't come off.
To remove the propeller, reverse the above pro-
cedure.

ADJUSTMENTS

TRIM ANGLE ADJUSTMENT

To help maintain steering stability and good
performance, always maintain the proper trim
angle as shown in the illustration. The appropri-
ate trim angle varies depending on the combi-
nation of the boat, engine, and propeller, as well
as operating conditions.
• Trim angle too small (Boat tends to "plow")
• Trim angle too large (Boat tends to "porpoise")
• Proper trim angle
