Product Details

This flat-plate trim tab anode helps protect compatible marine drive components from galvanic corrosion in fresh and saltwater environments. Its low-profile design provides clearance where a flat anode is required, including installations with limited space near the propeller.

Confirm fitment by matching the number stamped on your original anode or listed in your service manual. Catalog references identify this replacement family with Mercury Marine part numbers including 76214A5, 786214A2, 97-762145, and 97-76214Q5. The aftermarket Sierra reference 18-6016 is also associated with this Mercury Marine part family.

  • Flat trim tab anode design for compatible applications.
  • Suitable for marine use in fresh and saltwater environments.
  • Direct-replacement style installation when the original part-number and mounting arrangement match.
  • Verify the original part number, dimensions, mounting hole and material before ordering.

Compatibility Information

This anode should be used only when your original component or service documentation identifies one of the reference numbers above. Part-number co-occurrence alone does not establish fitment for every Mercury, Mariner, Force or MerCruiser model, so verify the exact model, year, serial range, drive type and mounting arrangement before purchase.

Check What to Confirm
Manufacturer reference 76214A5, 786214A2, 97-762145 or 97-76214Q5 appears in the service manual or on the original part.
Aftermarket reference Sierra 18-6016 is listed as the applicable replacement.
Physical fit Shape, mounting hole, bolt size, clearance and anode position match the original component.
Application details Engine or drive model, year, serial range and water-use conditions are compatible.

  • Mounting hardware only if shown in the product images or specifically stated with your order

Installation Notes

  1. Switch off the engine and disconnect the battery or main power supply before beginning work.
  2. Locate the existing trim tab anode and compare its shape, mounting hole and reference number with this replacement.
  3. Remove the retaining bolt and old anode. Keep the original hardware if replacement hardware is not supplied or if the original hardware is required for your application.
  4. Clean corrosion, paint and buildup from the mating surfaces. A clean contact surface is necessary for proper electrical continuity.
  5. Position the replacement anode in the same orientation as the original component.
  6. Install and tighten the retaining hardware according to the engine or drive manufacturer’s torque specification. Do not over-tighten.
  7. After installation, confirm that the anode has adequate clearance from the propeller and other moving parts.

Troubleshooting & FAQ

How do I confirm that this anode fits?

Match the number on your original anode or in your service manual with 76214A5, 786214A2, 97-762145, 97-76214Q5 or Sierra 18-6016. Also compare the physical shape, mounting hole, bolt and clearance. Model name or horsepower alone is not sufficient for confirmation.

Is this an OEM Mercury Marine part?

No. This listing is for an aftermarket replacement. Mercury Marine numbers are shown only as manufacturer reference numbers used to identify the applicable replacement family.

Why is an anode needed?

An anode is designed to corrode preferentially and help reduce galvanic corrosion of more valuable underwater metal components. Corrosion rate depends on water chemistry, electrical conditions, paint condition and bonding.

How often should I inspect or replace the anode?

Inspect it regularly and at least during routine seasonal maintenance. Replace it when it is substantially consumed, deeply pitted, loose, damaged or no longer provides adequate contact with the mounting surface. Actual replacement intervals vary by water conditions and vessel use.

Can this anode be used in freshwater and saltwater?

It is intended for marine use, but the correct anode material depends on the water type and the manufacturer’s application requirements. Confirm that zinc is appropriate for your specific installation before fitting it.

Can I install it myself?

Installation is usually straightforward when the replacement exactly matches the original part. Follow the engine or drive manufacturer’s service instructions, torque specification and safety procedures. Seek professional assistance if the mounting surface, hardware or fitment is uncertain.

Safety & Important Info

  • Verify the reference number, dimensions, mounting arrangement and clearance before ordering.
  • Do not rely on horsepower, brand or general model descriptions alone to confirm fitment.
  • This is an aftermarket replacement, not an OEM component.
  • Do not operate the boat if the anode is loose or interferes with the propeller or other moving parts.
