Use Of Electrical Accessories; Propeller Selection And Installation - Suzuki DF25A Owner's Manual

USE OF ELECTRICAL
ACCESSORIES
To use electrical accessories, you must pur-
chase a 70 AH or larger battery, rectifier and
related items. (Recoil starter model only).
NOTICE
If you connect electrical accessories directly
to the power receptacle of the motor, the elec-
trical accessories could be damaged.
Connect lights and electrical accessories for
the boat to the battery. Consult your autho-
rized Suzuki marine dealer for information
about correct wiring.
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.
NOTE:
On the models equipped with a receptacle,
detach the charging cord from the receptacle
and fit the cap to prevent water entry when not
using power supply.
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.
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.
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.
