Product Details
This sacrificial trim tab anode helps protect the lower casing and drive system of compatible Yamaha outboards from galvanic corrosion. It is intended for Yamaha 115 HP and 130 HP 2-stroke outboards, including the model families listed below, with applications documented from 1984 through 2004. The part also serves as the adjustable trim tab used to help counter propeller torque and improve steering balance.
This aftermarket replacement corresponds to Yamaha OEM part numbers 6E5-45371-01-00 and 664-45371-01-00. Sierra catalog reference 18-6097 is also documented for this application.
- Direct replacement-style fit for the documented Yamaha lower-casing applications.
- Single zinc trim tab anode; mounting bolt is not included.
- Zinc anodes are intended for saltwater applications. Use the material recommended for your boat's water conditions.
- Adjustable trim-tab design provides corrosion protection while helping counter steering torque.

What's in the Box
- 1 × Zinc trim tab anode
Mounting bolt is not included. Reuse the correct serviceable bolt only if it matches the required application and condition.
Installation Notes
- Secure the vessel, switch off the engine, disconnect the battery, and tilt the outboard to a safe service position.
- Locate the trim tab anode on the lower casing drive and note its orientation or adjustment position.
- Remove the mounting bolt and the worn anode. Replace the bolt if it is damaged, corroded, or does not meet the required specification.
- Clean the mating surface on the lower casing so the anode makes clean electrical contact. Do not apply paint or insulating coating between the anode and the mounting surface.
- Position the replacement anode in the same orientation as the original and install the correct mounting bolt.
- Tighten the bolt to the outboard manufacturer's service specification. Do not guess at torque values.
- After launching, check the anode and trim-tab adjustment during a controlled test. Readjust only according to the engine service procedure.
Troubleshooting & FAQ
How do I confirm that this anode fits my Yamaha outboard?
Confirm that your engine is a Yamaha 115 HP or 130 HP 2-stroke with the compatible lower-casing drive application. The most reliable check is matching the original OEM number 6E5-45371-01-00 or 664-45371-01-00 and comparing the original anode's shape, mounting location, and orientation.
Does this fit Yamaha F115 or other 4-stroke engines?
No 4-stroke fitment is established for this listing. The documented application is for Yamaha 115–130 HP 2-stroke lower-casing drive models. Verify the OEM number for any F115 or other 4-stroke engine before purchasing.
What are the signs that the old anode needs replacement?
Replace the anode when it is substantially consumed, deeply pitted, loose, cracked, or no longer provides a sound mounting and electrical-contact surface. Inspect it regularly because corrosion rates vary with salinity, electrical conditions, storage, and boat usage.
Does this anode help with steering?
Yes. In addition to corrosion protection, the trim tab can be adjusted to help counter propeller torque and reduce a pull to one side. Follow the outboard manufacturer's adjustment procedure and test the boat carefully after installation.
Is the mounting bolt included?
No. This package contains one zinc trim tab anode only. The documented bolt is a separate component, referenced as Yamaha 90105-10M00-00 with M10 × 1.25 × 45 mm dimensions.
Why is this anode made of zinc?
Zinc is commonly used as a sacrificial anode in saltwater. It corrodes preferentially to help protect more critical submerged metal components. Material selection should match the boat's actual water conditions.
Is this an OEM part?
This listing is for an aftermarket replacement, not a Yamaha-branded OEM part. It is identified by the documented OEM replacement references and should be checked against the original component before installation.
Safety & Important Information
- Verify the OEM number, engine stroke, model code, year, mounting position, and physical dimensions before ordering.
- Do not install this part on an engine when the original component or mounting arrangement differs.
- Use zinc for the documented saltwater application; consult the engine or boat manufacturer when operating in freshwater or brackish water.
- Use the correct mounting bolt and follow the manufacturer's service torque and adjustment instructions.
- Professional installation is recommended when the correct fitment, corrosion protection, or trim-tab adjustment cannot be confirmed.
