Upper Gimbal Steering Swivel Shaft for MerCruiser Sterndrives

Eliminate steering "slop" and restore precise control to your boat with this heavy-duty aftermarket Upper Swivel Steering Shaft by FASWORX. Engineered as a direct drop-in replacement for worn or corroded factory pins, this component fixes the common loose steering issues associated with aging transom assemblies before they cause catastrophic seal failure and water intrusion.

Built to Outlast OEM Specifications

While standard shafts often fall victim to harsh saltwater corrosion and premature pitting, this FASWORX upgrade is machined from premium-grade, heat-treated marine stainless steel. It provides maximum torsional strength and exceptional resistance against rust, ensuring smooth steering mechanics and structural integrity over seasons of hard runtime.
