This hydraulic steering cylinder is designed for outboard powered boats up to 300 horsepower, including center console, offshore fishing, bass, and flats boats. Its front mount design installs beneath the steering arm for a compact fit. The housing is built from high-strength aluminum alloy that resists corrosion and seawater erosion for long-term durability. It operates at a maximum working pressure of 10.3 MPa or 1500 Psi and includes a built-in two-way locking valve that eliminates rebound torque during turns and supports independent engine tilt on twin or triple engine setups. A redesigned 8-hole end gland seal with positionable stainless steel Orb fittings simplifies hose routing. This unit is a direct replacement for HC5345-3 style cylinders and ships without hydraulic hose or helm, which must be purchased separately. Wipe the housing clean and check fittings periodically to keep steering performance smooth and reliable.
