Quicksilver 865344A01 Clutch Assembly for MerCruiser Bravo Drives

The Quicksilver 865344A01 is a genuine OEM clutch assembly designed for MerCruiser Bravo sterndrive applications. This critical component, also known as a cone clutch or clutch dog, is the sliding sleeve assembly that engages forward and reverse gears within the upper gear housing of Bravo drives.

Key Features:

• Genuine Mercury Marine OEM part, manufactured from stainless steel construction
• Universal fitment for Bravo One, Two, and Three drive models serial number 0W250000 and up
• Also fits Bravo X and Bravo XR drives (0W240000 and up)
• Supersedes previous part number 861781A1
• Features vertical grooves for positive engagement with gear cups
• Includes garter springs for proper clutch operation

This clutch assembly moves up and down on a spiral splined shaft to engage forward and reverse driven gears. The cone-shaped surface with lateral grooves locks into matching tapered rings inside the gear cups, transmitting power from the engine to the propeller. Over time, these grooves can wear flat and glazed, causing delayed or poor shifting response, particularly when the drive is hot. The 865344A01 represents the current-generation design and is covered by Mercury Marine's standard warranty against defects and workmanship.

Compatibility: Fits MerCruiser Bravo One, Two, Three, X, XR, and XR Sportmaster drives, as well as certain high-performance and integrated transom assemblies from the specified serial number ranges.
