Packaged Outboard Hydraulic Steering OH-350-CR — Complete Single-Station Kit by Advance Trident

Trust your boat’s steering to a purpose-built, all-in-one hydraulic system designed for dependable control in any marine conditions. The Packaged Outboard Hydraulic Steering OH-350-CR is a complete, single-station kit engineered for quick installation and long-term reliability on both saltwater and freshwater vessels. With a broad ambient temperature tolerance (-20°C to +60°C) and marine-grade components, it keeps your helm responsive from chilly dawns to hot afternoons.

What’s in the box

• HP-27 hydraulic helm pump — a compact axial-piston unit that converts wheel movement into steady hydraulic force.
• OC-350 front-mount single balanced cylinder — delivers linear, predictable steering motion to the outboard.
• CT-7.5 hose kit (7.5 m total) with factory-crimped ends — flexible routing with secure, leak-minimized connections.
• HO-150 hydraulic oil — 2 litres of high-viscosity-index fluid for smooth, consistent performance.

Why this kit stands out

• Broad temperature tolerance — designed to stay responsive in extreme conditions, from icy mornings to hot, humid days.
• Marine-ready construction — components chosen and finished to endure saltwater spray, vibration, and long run times.
• Integrated safety and reliability — a lock valve prevents unintended steering movement, while a pressure-relief valve protects the system from overpressure.
• All-in-one, ready-to-install package — minimizes installation time and eliminates the guesswork of sourcing individual parts.
• EU-regulatory alignment — complies with the Recreational Craft and Personal Watercraft Directive 2013/53/EU and EN ISO 10592:1995 / Al:2000 for safety and performance.

How it works on your boat

Turning the helm engages the HP-27 pump, pushing hydraulic fluid through the CT-7.5 hose assembly to the OC-350 cylinder. The cylinder converts fluid movement into precise, linear outboard steering. The closed-loop design maintains consistent response from the first inch of wheel travel to the moment you settle on your course, delivering predictable handling in every turn.

Ideal for

• Casual and seasoned boaters seeking confident, low-effort steering for single-outboard configurations.
• Recreational craft and personal watercraft setups where up to 350 HP performance is appropriate.
• Upgrades or new builds that benefit from a compact, packaged hydraulic steering solution that reduces installation complexity.

Practical considerations and tips

With factory-crimped hose ends and matched components, this kit minimizes leak points and simplifies maintenance. Regular inspection for wear, proper fluid level in the HO-150 reservoir, and adherence to the included service guidelines will help preserve steering feel and reliability across seasons. Because it is marine-grade and EU-compliant, this system is designed to deliver consistent performance in diverse water conditions and regulatory environments.
