893929A01 Manual Release Valve for Mercury Mariner Outboard Tilt Trim 30-300 HP
893929A01 Manual Release Valve for Mercury Mariner Outboard Tilt Trim 30-300 HP
Product Overview
Tilt and trim manual release valve for Mercury and Mariner outboards, and for Chrysler / Force / US Marine applications. Replaces Mercury 893929A01 / 811618A1 / 812843A1 / 813442A1 / 813442A2 (Sierra 18-6751) and fits 2-stroke and 4-stroke models from 30 HP to 300 HP. The manual release valve lets you lower the outboard by hand when the trim system has no power — a common failure point that seizes or weeps fluid over time.
