⚙️ Key Features

• Component of mounting kit 21211763
• Provides mechanical retention and electrical bonding
• Factory thread and installed length
• Designed for metal-hull corrosion-protection systems
• Supplied as one rod only
• 2 used per assembly

🔌 Function

The rod secures and bonds the anode-mounting components so sacrificial corrosion protection can operate correctly.

⚠️ Common Signs of Failure

• Corroded or damaged threads
• Loose anode assembly
• Poor electrical bonding
• Protected components corroding despite anode material remaining
• Water leakage around damaged O-rings

🛠️ Service Notes

• Check the rod for straightness and its ends for wear or damage before fitting — a bent rod cannot be corrected by refitting and will bind or carry its load off-line
• Note its orientation and fitted position on removal; many rods are handed or are only correct one way round
• Fit without forcing, secure all locknuts, pins and clips, and tighten to the figures in the workshop manual for your engine
• Check it moves freely through its full travel by hand, with no tight spot or fouling, before the engine is run
