Mercury 1.25-Inch Propeller Shaft 8M0142764

Mercury Propeller Shaft 8M0142764 is an OEM gearcase component designed for select Mercury Verado and high-performance outboard gearcases. Mercury parts diagrams identify this as the 1.25-inch propeller shaft, distinguishing it from the 1-inch propeller shaft used in other configurations.

Compatible with select applications including:

• Mercury 200-300 HP L6 Verado
• Mercury 350 HP Verado
• Mercury 400 HP L6 Verado
• Mercury Racing 250R and 300R
• Select Mercury Racing 400R applications
• Compatible 5.44-inch torpedo gearcases

The propeller shaft transfers power from the gear set to the propeller while supporting the associated clutch, bearing, thrust, and sealing components within the gearcase. Mercury diagrams show 8M0142764 in both standard and counter-rotation gear housing configurations, so fitment should be determined by the complete gearcase configuration rather than horsepower alone.

This is the propeller shaft only. Bearings, seals, thrust components, gears, and related gearcase hardware are sold separately.

Supersedes/Replaces: 8M0053111, 8M0073667, 8M0103300.
