MgDuff Magnesium Teardrop Weld-On Hull and Rudder Anodes – MD76 / MD77

The MgDuff Magnesium Teardrop Anode is a sacrificial anode designed to protect boat hulls and rudders against galvanic corrosion. Manufactured from magnesium, it features a teardrop-shaped body with an extended mounting strip for installation on the vessel.

The range includes two models: MD76 and MD77. They differ in body dimensions, mounting strip length and mounting hole spacing. Both versions are designed for underwater hull and rudder applications, providing sacrificial corrosion protection for marine metal components.

Dimensions and Model Selection

The MgDuff magnesium anode range includes two teardrop-shaped models with different body dimensions and mounting arrangements. Body dimensions are specified as length × width × height.

MD76 (1795): Magnesium anode measuring 114 × 76 × 32 mm, with a mounting strip length of 160 mm and mounting hole spacing of 140 mm.
MD77 (1796): Magnesium anode measuring 157 × 83 × 41 mm, with a mounting strip length of 230 mm and mounting hole spacing of 200 mm.

When selecting an anode, consider the body dimensions, mounting strip length and centre-to-centre mounting hole spacing to match the required installation dimensions.

Construction and Installation

Both models feature a teardrop-shaped magnesium body with a mounting strip extending beyond the anode. The strip features mounting holes, with different hole spacings depending on the model.

Anode Body: Teardrop-shaped magnesium construction.
Mounting Arrangement: Extended strip with mounting holes.
Strip Length: 160 mm for MD76 and 230 mm for MD77.
Hole Spacing: 140 mm for MD76 and 200 mm for MD77.
Installation Location: Boat hull or rudder.
Application: Underwater corrosion protection.

Galvanic Corrosion Protection

The magnesium anode functions as a sacrificial component, corroding preferentially to help protect other metal parts of the vessel against galvanic corrosion.

The MD76 model is described for saltwater environments. The MD77 model is described for use in both freshwater and saltwater environments.

The two models provide different body sizes and mounting dimensions for hull and rudder installations.
