Quicksilver 893929A01 Relief Valve Kit for Mercury & Mariner Power Trim/Tilt Systems

The Quicksilver 893929A01 Relief Valve Kit is a genuine OEM replacement relief valve designed for Mercury and Mariner hydraulic power trim and tilt systems. As a factory-original Quicksilver part, it ensures a precise fit and restores full hydraulic system performance without the guesswork of aftermarket alternatives.

This relief valve kit regulates hydraulic pressure within the trim and tilt assembly, providing stable position hold and smooth manual release control. It is commonly used to resolve issues such as trim slippage, slow drop-back under load, or a trim system that fails to hold position — all common symptoms of a worn or leaking internal valve.
