This Tecnoseal zinc anode for 70 mm propeller shaft is a split shaft anode, which is mounted around the shaft to protect the shaft and associated hardware from galvanic corrosion.
The anode corrodes instead of the more expensive metal parts and is designed for propeller shafts with a 70 mm diameter. It is used on medium and large motorboats with powerful shaft installations.
During installation, the two halves are placed around the shaft and tightened together with through-bolts. The contact surface must be cleaned of paint, rust, and fouling to ensure direct metal-to-metal contact.
