Let’s Dive into Sierra International 182146 182146 Yoke
The Sierra International 182146 Yoke is a critical component in the drivetrain of many popular sterndrive systems. Manufactured by Sierra International, a trusted name in aftermarket marine parts, this yoke is designed to connect the engine’s power to the outdrive unit, transferring torque to the propeller. Its wide compatibility across Mercruiser and OMC Cobra stern drives makes it a versatile replacement part for boat owners and mechanics.
My own journey to finding the Sierra International 182146 Yoke began when I noticed excessive play in the driveline of my project boat, a classic 1988 Sea Ray with an OMC Cobra outdrive.

After confirming the part number through cross-referencing guides, I chose the Sierra International yoke due to its reputation for quality and compatibility.
Upon unboxing, the Sierra International 182146 Yoke immediately impressed with its robust construction. The materials felt strong and durable, suggesting a long service life. Its weight felt appropriate for the task, instilling confidence in its ability to handle the engine’s power.
While several yokes are available on the market, including those from GLM and Mallory, I chose the Sierra International part because of its direct interchangeability with both Mercruiser and OMC part numbers. This wide compatibility, coupled with the included O-rings, streamlined the replacement process. My initial impression was one of relief – I felt I’d found a reliable and correctly specified part to get my boat back on the water.
