Product Description
The Mercury MerCruiser Quicksilver 11-896963 is a genuine Mercury Marine OEM M12 metric hex nut used as diagram-specific hardware across a wide range of Mercury outboard assemblies. The manufacturer part number is 896963, and the part is listed as NUT (M12) with Mercury Marine as the manufacturer.

Application Compatibility
This M12 nut is used across multiple Mercury outboard model families where the exact parts diagram calls for 11-896963 / 896963. Listed where-used applications include select 50 EFI and 60 EFI 4-cylinder FourStroke models, 75/90 DFI 1.5L 3-cylinder models, 75/80/90 EFI FourStroke models, 80 Jet 1.5L models, and multiple 3.0L / 3.2L DFI and EFI outboard applications including 200, 225, 250, 250XS, 300XS, Pro XS, Sport XS, SeaPro, and Marathon variants by serial range.
Use this nut only where the Mercury parts diagram, engine serial number, and assembly location call for 11-896963.
Serial Number Fitment Notice
Confirm fitment by Mercury engine serial number and diagram location before ordering. Mercury uses similar-looking M12 and M14 hardware across different steering, swivel bracket, driveshaft housing, mount, and midsection assemblies, so matching the thread size alone is not enough.
When This Part Needs Replacement
Replace this nut if the original fastener is missing, rounded, corroded, cross-threaded, stretched, or removed during service of the related mount, bracket, steering arm, driveshaft housing, or midsection assembly. Hardware in high-vibration outboard areas should not be reused if the threads, flats, locking surface, or seating face are damaged.
Installation Notes
Install only in the exact Mercury diagram location that calls for 11-896963 / 896963. Inspect the mating bolt or stud threads before installation, and replace any worn washers, bolts, bushings, mounts, or bracket hardware shown in the same diagram if they are damaged. Follow the Mercury service manual for the correct torque procedure and any required locking method for the specific assembly.

Parts Desk Insight
This is a small hardware item, but it should still be matched by part number rather than by appearance. Mercury uses many metric nuts with similar outside dimensions across different outboard assemblies, and using the wrong fastener can affect clamp load, thread engagement, or service fit in mount and steering-related locations.
