Propeller Selection And Installation; Propeller Selection - Suzuki DF4 Manuel Du Propriétaire

After installing the motor, check to make sure
that steering and tilt movement are not
obstructed by any part of the boat. Also make
sure that the battery cable (if provided) doesn't
interfere with movement of the motor.
 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.
NOTICE
If you attempt to mount the outboard to
the transom without having mechanical
experience 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.

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 the performance. Your
operating load will also affect propeller selec-
tion. Smaller loads generally require larger-
pitch propellers; larger loads generally require
smaller-pitch propellers. Your authorized Suzuki
Marine Dealer will assist you in selecting a suit-
able propeller for your boat.
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 suit-
able propeller 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.
