USE OF ELECTRICAL
ACCESSORIES
The amount of power (DC12V) available for
accessories, however, depends on the operat-
ing condition of the motor. For getting a detailed
information, 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.
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.
