Mercury Marine Engine Coupler Assembly V6 & V8 Gas Bravo
The Quicksilver 861523A11 is a genuine OEM engine coupler assembly manufactured by Mercury Marine, specifically designed for Mercruiser sterndrive applications pairing GM V-6 and V-8 gas engines with Bravo I, II, and III drive units. As a factory-original component — not an aftermarket substitute — it delivers the precise fit, long-term durability, and reliable performance that Mercury Marine engineering demands.
This coupler features hardened steel splines engineered to handle the torque and demanding load conditions typical of marine sterndrive use, particularly in low-speed and high-work scenarios. The design accommodates both metric and SAE attaching screws, providing installation flexibility for a wide range of setups. The assembly includes a long hub/shaft configuration suitable for flywheel-mount applications.
Compatibility should be confirmed using the engine serial number and Bravo drive model prior to ordering. This coupler supersedes part number 861523A1. Mercury Marine and Quicksilver products carry a one-year factory warranty against defects in materials and workmanship. Serialized items must be installed by an authorized dealer for warranty to be valid.
