SUB BATTERY CABLE
The sub battery cable
1
is used to supply volt-
age to the engine control system. In the midst
of the cable, a 15 A fuse
2
is provided to pro-
tect the control circuit.
If the sub battery cable is not correctly con-
nected to the battery, engine cannot be started.
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.
CAUTION
Use of too much power for electrical
accessories under certain operating con-
ditions can cause the battery to dis-
charge.
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.
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.
CAUTION
Installing a propeller with pitch either too
high or too low will cause incorrect maxi-
mum engine speed, which may result in
severe damage to the motor.
