Galvanic protection
The Grand Soleil 46.3' is equipped with the following anti-
corrosion anodes, protecting the metal parts exposed to
galvanic currents.
◊
on the "S drive" propeller shaft
◊
on the main engine (ref. to the Engine Owner's Manual)
◊
in the water heater (ref. to the Water Heater Owner's Manual)
The anodes must be carefully controlled as follows:
Propeller Shaft
The propeller shaft anode is exposed more than any other to galvanic
currents. It is fitted on the shaft itself, in front of the propeller.
• It should be checked each time the boat is hauled out and at least
2 or 3 times during the season. If the anode shows more than 30%
loss of mass, replace it as soon as possible. In order to assess the
degree of corrosion, compare it with a new anode.
• The same precautions should be applied to the propeller anode.
Main engine
Refer to the engine manufacturer owner’s manual for the location
and care of the main engine anodes.
• Replace as needed.
Water heater
Refer to the manufacturer owner’s manual for the positioning and
care of the water heater anodes.
• Replace as needed
General recommendations
• If one or more anodes corrode rapidly, this may indicate possible
electrical dispersion or may be due to the proximity of electron
conductive masses (such as large motor yachts or ships) in water
with a high salinity gradient.
- Have qualified marine electrician check the electrical system
and eliminate dispersions or install removable, dockside anodes.
