Installation Notes

1. Disconnect battery and remove propeller for safety.
2. Inspect the lower unit trim tab mounting surface and remove any old anode or corrosion buildup.
3. Clean the mounting area thoroughly with a wire brush and degreaser to ensure metal-to-metal contact.
4. Position the new aluminum anode plate on the trim tab and align mounting holes.
5. Secure with appropriate fasteners, tightening evenly to manufacturer torque specifications.
6. Reinstall propeller and reconnect battery. Inspect anode periodically and replace when 50% or more is consumed.

Troubleshooting & FAQ

How do I know when to replace the anode?

Replace the anode when it has eroded to approximately 50% of its original size. Regular inspection every few months is recommended, especially in saltwater environments where corrosion occurs faster.

Will this fit my specific drive or outboard model?

This anode is compatible with MerCruiser AlphaOne Gen II, Bravo I, II, III, X, XR, and XZ drives, as well as Mercury/Mariner 35-300hp and Force 90-120hp (1995+). Always verify your part number and mounting configuration before ordering.

Can I use this in freshwater?

Yes, aluminum anodes work in both saltwater and freshwater. However, zinc anodes are typically preferred for saltwater-only use, while aluminum anodes offer better versatility across mixed environments.

Do I need to remove paint from the mounting surface?

Yes. For the anode to function properly, there must be bare metal-to-metal contact between the anode and the lower unit. Remove all paint, corrosion, or coatings from the mounting area.

What causes rapid anode wear?

Excessive galvanic corrosion can be caused by stray electrical currents, faulty grounding, or proximity to dissimilar metals. If your anode wears unusually fast, have your electrical system inspected.

Safety & Important Info

• Verify images/specifications against your original part. If anything differs—even if your model appears compatible—do not purchase.
• This is an aftermarket replacement, not an OEM component.
• Professional installation is recommended for safety and performance.
