Available Materials
- Tecnoseal 00478 – Zinc: 1.08 kg sacrificial anode.
- Tecnoseal 00478AL – Aluminium: 0.44 kg sacrificial anode.
Both versions share the same external dimensions and mounting configuration. Select the appropriate anode material according to the vessel's corrosion protection requirements and the manufacturer's recommendations.
Mounting Configuration
The anodes feature a stepped internal recess with mounting diameters Ø1 = 40 mm and Ø2 = 18 mm, together with a recess dimension h1 of 44 mm.
The manufacturer's catalogue specifies a shaft size range of Ø55–70 mm. Before ordering, compare the anode dimensions, mounting profile and shaft specification with the existing Ferretti propeller assembly.
Inspection and Replacement
Inspect the sacrificial anode periodically for material consumption and replace it when necessary. During installation, ensure suitable electrical contact with the metallic components requiring corrosion protection.
Supply
One Tecnoseal Ferretti 620 propeller anode in the selected material.
