What This Anode Kit is Used For
The Mercury 8M0107547 aluminum anode kit is designed to help protect compatible Mercury and Mariner FourStroke outboards from galvanic corrosion.
Sacrificial anodes help reduce corrosion damage caused by exposure to freshwater, saltwater, and stray electrical current in marine environments.
Regular inspection and replacement of anodes is recommended as part of routine outboard maintenance.
Why Use Aluminum Anodes?
- Freshwater applications
- Saltwater applications
- Brackish water environments
Why Replace Sacrificial Anodes?
Sacrificial anodes are designed to corrode over time in order to help protect expensive outboard components from galvanic corrosion.
Replacing worn anodes during regular maintenance helps extend the life of your gearcase and other underwater metal components.
Mercury recommends periodic inspection and replacement when corrosion, pitting, or excessive material loss is visible.

What This Anode Kit is Used For
The Mercury 8M0107549 aluminum anode kit is used to help protect compatible Mercury and Mariner FourStroke outboards from galvanic corrosion and electrolysis damage.
Sacrificial anodes are designed to corrode before expensive aluminum outboard and gearcase components. Regular inspection and replacement of worn anodes helps extend the service life of your outboard.
These OEM Mercury aluminum anodes are designed for use in freshwater and saltwater.

Why Replace Outboard Anodes?
Outboard anodes are sacrificial corrosion components that help protect expensive aluminum engine and gearcase components from galvanic corrosion.
Inspect anodes periodically and replace them when you see corrosion, pitting, erosion, or heavy wear. Worn anodes offer less protection and can leave the gearcase and other aluminum components exposed to corrosion.

Mercury Lower Unit Components
Mercury V6 V8 Racing Verado Propeller Shaft 8M012764
Mercury 8M012764 is a propeller shaft used in select larger Mercury gearcase applications, including high-performance V6 and V8 Racing outboards and Verado L6 models equipped with the 5.44 inch gearcase.
This shaft replaces earlier Mercury numbers 8M0103300, 8M0073667, and 8M0053111. These supersessions represent updated versions of the same physical propeller shaft, but exact fitment should always be verified by engine serial number, gearcase size, and lower unit configuration.
Compatible Applications
| Brand | Engine / System | Application | Fitment Note |
|---|---|---|---|
| Mercury Racing | V6 / V8 250-300R 4.6L outboards | Lower unit propeller shaft | Verify by serial number, gearcase, and prop shaft configuration |
| Mercury Verado | Inline-6 Verado with 5.44 inch gearcase | Heavy-duty lower unit propeller shaft | Confirm gearcase size and serial number before ordering |
Important Fitment Note
Propeller shaft fitment depends on the exact gearcase, gear ratio, shaft length, spline configuration, and engine serial number. Always confirm compatibility using your OEM lower unit diagram before ordering.
OEM & Cross Reference Numbers
| Current Mercury Number | 8M012764 |
| Superseded Mercury Numbers | 8M0103300, 8M0073667, 8M0053111 |
| Description | Propeller Shaft |
What This Part Is Used For
The propeller shaft transfers power from the lower unit gear set to the propeller. It supports the propeller hub and must run true to maintain smooth power delivery through the gearcase.
Replacement may be needed when the shaft is bent, worn, damaged at the splines, or being serviced during a lower unit rebuild. High-performance and larger gearcase applications require the correct shaft to match the torque load and gearcase design.
Key Features and Benefits
- Propeller shaft for select Mercury Racing and Verado lower units
- Fits select V6 / V8 250-300R 4.6L high-performance outboard applications
- Used on select Verado Inline-4 and Inline-6 models with 5.44 inch gearcases
- Replaces Mercury 8M0103300, 8M0073667, and 8M0053111
- Designed for larger gearcase applications where strength and correct fitment are critical
FAQ
What is Mercury 8M012764?
Mercury 8M012764 is a propeller shaft for select Mercury Racing, Verado, and larger 5.44 inch gearcase applications.

It replaces Mercury 8M0103300, 8M0073667, and 8M0053111.
Does this fit all Mercury 250-300HP outboards?
No. This shaft is for specific V6 / V8 Racing and Verado 5.44 inch gearcase applications. Verify by serial number and lower unit diagram.
Why should I verify the serial number?
Gearcase parts can vary by gear ratio, prop shaft size, shaft length, and model configuration, even within the same horsepower family.
