Troubleshooting & FAQ
How do I know if this anode fits my engine?
This anode fits a wide range of Mercury/Mariner outboards (35-300 HP, 1995+), Force outboards (90/120 HP, 1995+), and MerCruiser Alpha/Bravo drives. The best way to confirm is by matching the OEM part number (e.g., 97-76214Q5, 97-76214T5) from your service manual to the numbers in our Part Number Matrix.
What’s the difference between zinc and aluminum anodes?
Zinc anodes, like this one, are traditionally used for saltwater applications. Aluminum anodes are formulated for saltwater and brackish water, and are the standard for modern Mercury/MerCruiser engines. This zinc alloy part provides reliable protection in both fresh and salt water.
How often should I replace my trim tab anode?
Inspect your anodes at least once a year or every 100 hours of operation. You should replace them when they are 50% corroded or consumed. Replacement frequency depends on water salinity, temperature, and electrical currents in your marina.
What are the signs of a worn-out anode?
A worn-out anode will appear heavily pitted, physically smaller, and may have a chalky white coating. If the anode is gone or mostly eroded, your engine's other metal components are at risk of galvanic corrosion damage.
Why is a flat anode plate better for some setups?
This flat plate design offers increased clearance compared to standard or finned anodes. This is particularly beneficial for boats equipped with high-rake propellers, as it helps prevent the propeller blades from striking the anode during operation.
Can I install this trim tab anode myself?
Yes, this is a straightforward DIY task for most boat owners. It involves removing one bolt, cleaning the mounting surface, and securing the new anode. However, if you are unsure, professional installation is always recommended.
