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| Superseded Mercury Numbers | 8M0103300, 8M0073667, 8M0053111 |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.
