NOTICE
The electrical system or its components
may be damaged if proper battery pre-
cautions are not followed.
• Be sure to attach battery leads cor-
rectly.
• Do not disconnect battery leads from
the battery while the engine is running.
USE OF ELECTRICAL ACCESSORIES
The amount of power (12V DC) available for
accessories depends on the operating condi-
tion of the motor. For getting a detailed informa-
tion, please inquire of your authorized Suzuki
Marine Dealer.
NOTE:
Use of too much power for electrical accesso-
ries under certain operating conditions can
cause the battery to discharge.
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:
DF40A
DF50A
DF60A
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.
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.
