VEVOR Hydraulic Steering Cylinder for Outboards 300HP, Front-Mount, 1500 PSI Two-Way Lock

VEVOR's front-mount hydraulic steering cylinder provides outboard boats up to 300HP with durable, high-pressure steering control without including a helm pump or steering hose.

This front-mount hydraulic cylinder is engineered for single and twin outboard engines up to 300 horsepower. Built with a high-strength aluminum alloy casing, robust seals, and a built-in two-way lock, it resists corrosion and repeated compression while delivering up to 10.3 MPa (≈1500 PSI) working pressure. The unit ships as the cylinder only — helm pump and hoses are not included — making it ideal for retrofits, replacements, or custom hydraulic steering builds.

How does this cylinder handle heavy-duty steering loads?

The HC5358-3 / HC5345-3 is rated to a maximum working pressure of 10.3 MPa (about 1500 PSI), giving it the capacity to manage the torque and forces from outboard motors up to 300HP. Internally, the cylinder uses durable seals and a two-way locking valve to minimize rebound and maintain predictable steering feel under load.

• Max working pressure: 10.3 MPa / 1500 PSI
• Built-in two-way lock to reduce rebound torque
• Designed for single or twin outboard setups up to 300HP

What features protect the cylinder from the marine environment?

Corrosion resistance and long-term seal performance are central to this design. The housing is made from high-strength aluminum alloy with surface treatment for wear and seawater resistance, while the sealing system resists compression set to keep fluid contained and performance consistent over time.

• Aluminum alloy casing with anti-corrosion surface finish
• Advanced sealing for superior crush/compression resistance
• Stainless steel O-ring fittings for durable hose routing

How easy is installation and integration with my existing setup?

The cylinder is intended as a front-mount replacement or upgrade and includes positionable stainless steel ORB fittings to simplify hose routing. Because the package contains only the cylinder, you can pair it with compatible helm pumps and hoses to match your boat’s configuration or to suit a twin-engine layout.

• Includes positionable stainless steel O-Ring (ORB) fittings
• Front-mount design for standard outboard transom installations
• Ships as cylinder only — select helm pump and hoses separately

Will this work for my boat type and horsepower?

The HC5345-3 variant is suitable for many outboard-powered vessels commonly used in recreational and sport fishing. It’s designed for center consoles, runabouts, cruisers, offshore fishing boats, bass boats, flats boats and similar craft, up to a combined engine rating of 300HP.

• Suitable for center consoles, runabouts, cruisers, and fishing boats
• Rated for single or twin engines up to 300HP
• Common retrofit option for both recreational and light-commercial boats

Who is this for: VEVOR’s front-mount hydraulic steering cylinder is aimed at boat owners, marine mechanics, and DIY installers who need a robust, corrosion-resistant steering cylinder for outboards up to 300HP. It suits people replacing a worn cylinder, upgrading to a higher-pressure component, or building a custom hydraulic steering system — provided you supply a compatible helm pump and hoses for a complete installation.
