After installing the motor, check to make sure
that steering and tilt movement are not
obstructed by any part of the boat.
NOTICE
If you attempt to mount the outboard to the
transom without having mechanical experi-
ence or without being certain where to drill
holes, you can seriously damage the boat.
If you do not have mechanical experience or
are not sure of where to drill holes in the
boat’s transom, you should have your motor
mounted by your authorized Suzuki marine
dealer.
WARNING
If the motor is not properly secured to the
transom, it can come off.
Be sure to bolt the motor to the transom. The
motor may come off if it is held only by the
clamp screws. Occasionally check the clamp
screws for tightness.
PROPELLER SELECTION
AND INSTALLATION
PROPELLER SELECTION
It is essential to use a propeller on your out-
board motor that is properly matched to your
boat’s operating characteristics. The speed of
the engine when you operate your boat at full
throttle depends on the propeller you use.
Excessive engine speed can seriously damage
the motor, while low engine speed at full throttle
will adversely affect performance. Your operat-
ing load will also affect propeller selection.
Smaller loads generally require larger-pitch pro-
pellers; larger loads generally require smaller-
pitch propellers. Your authorized Suzuki Marine
Dealer will assist you in selecting a suitable pro-
peller for your boat.
You can determine if your propeller is appropri-
ate for use with your boat by using a tachome-
ter to measure engine speed when operating
your boat at full throttle, under minimum load
conditions. If you are using an appropriate pro-
peller, the engine speed will be within the fol-
lowing range:
If the engine speed is not within this range, con-
sult your authorized Suzuki Marine Dealer to
determine which propeller size is best for you.
NOTICE
Installing a propeller with either too much or
too little pitch will cause incorrect maximum
engine speed, which may result in severe
damage to the motor.
Ask your authorized Suzuki marine dealer to
assist you in selecting a suitable propeller for
your boat.
