Product Description
Fin-Nor AM146-01 Shift Shaft – Marquesa 2-Speed MA20II & MA30II Replacement Part
Product Overview
Restore the versatile dual-gear performance of your lever drag reel with this genuine Fin-Nor AM146-01 Shift Shaft. Engineered specifically for the Fin-Nor Marquesa 2-Speed Series (MA20II and MA30II), this internal shaft is the central component of the high/low gear shifting mechanism.
The shift shaft engages the pinion and drive gears, allowing anglers to switch instantly between a high-speed retrieve for clearing lines and a low-speed crank for winching up heavy bottom fish. If your reel is stuck in one gear, refuses to shift smoothly, or feels "mushy" when pressing the shift button, a bent or worn shift shaft is a likely cause. Installing this factory-original part ensures your reel operates with the crisp, mechanical reliability needed for big game fishing.

Schematic Reference
To identify the correct orientation of the shift springs and keys relative to this shaft, please consult the official reel diagrams. You can locate the detailed schematic for the Fin-Nor Marquesa MA20II and MA30II at www.reelschematic.com.
Note: The shifting mechanism is complex and involves small springs and keys. We recommend applying a light coat of marine grease to the shaft during installation to ensure smooth sliding action.
