Sacrificial anode.
To protect the motor against electrochemical corrosion, due to
the presence in its structure of many different materials, a
sacrificial anode has been applied.
The anode will be subject to a strong corrosion, so you have to
remove the scales from the surfaces of the anode periodically.
Failure to clean it, will affect its effectiveness.
Do not paint the anode, for this would render it
ineffective.
When the corrosion compromise its functionality, you have to
replace it.

Replacement of the propeller.
The propeller is one of the components, which have a great
influence upon the performance of the motor. An unsuitable or
damaged propeller can cause serious damages to the motor
besides reducing the performance.
For a careful choice of the propeller contact a SELVA
MARINE service point.
To replace the propeller do as follows:
-
Wait until the motor has cooled down and remove the top
cowling ;
-
Remove the spark-plug cap, to avoid an accidental
start during the operations of replacement of the
propeller ;
-
Place the gear-shift lever in the neutral position "N" ;
-
Protect your hands using strong gloves and insert a
wooden lump between the propeller blades and the anticavitation
plate, to keep the propeller still ;
-
Remove the self stopping nut, the washer and the propeller
-
Spread the propeller shaft with water-repellent grease ;
-
Make sure, that the drive propeller pin is centred on the
shaft;
-
By hand insert the propeller making sure that it gets
correctly into the drive pin ;
-
Insert the washer and by hand screw the self-locking nut ;
-
Insert a wooden lump between the propeller blades and the
anti-cavitation plate ;
-
Keep the propeller pressed against the pin and screw tight the
nut. Fig. 63.
