Checking Protective Anodes
Volvo
Penta IPS drive units are protected against gal-
vanic corrosion by two anodes. One is installed in the
exhaust system (iron) and the other on the transom
(aluminum).
IMPORTANT!
Make sure the anode has good metallic contact with
the drive unit. Never paint the protection anodes.
IMPORTANT!
Do not connect Volvo Penta IPS units to each other.
Not valid for ACP, see more about ACP.
IMPORTANT!
Do not connect the Volvo Penta IPS units to the engine
or any other components on board.
IMPORTANT!
Do not connect any other equipment to the Volvo
Penta IPS transom-mounted anode.
IMPORTANT!
The anode must be insulated from the hull if the latter
is made of conductive material such as aluminum or
steel.
Propellers
The propellers are made of the same material as the
drive units and are electrically connected to them.
Paint the IPS propellers
Volvo Penta recommends the propellers to be painted.
This will reduce anode consumption as the bronze sur-
face exposed to water is reduced significantly by exter-
nal painting. In order for the paint to adhere to the pro-
pellers a suitable base coat is recommended before
antifouling paint is applied. Any high-speed marine
antifouling should be chosen, Prop-Speed recom-
mended.
