VEVOR Hydraulic Steering Cylinder for Outboard Boats 150HP Front-Mount, 197mm Stroke, ORB Fittings

VEVOR HC4645H is a front-mount hydraulic steering cylinder engineered for single-outboard boats up to 150HP, providing durable, crush-resistant steering with a built-in two-way lock and ORB fittings for tidy hose routing.

This compact hydraulic outboard steering cylinder is designed for center-console, offshore fishing, bass, flats, and other single-outboard boats where a front-mount Yamaha-style installation is required. Built from high-strength aluminum alloy and finished for corrosion resistance, the HC4645H balances force, travel, and volume—making it suitable for common recreational and light-commercial outboard setups. The cylinder ships with two hoses and is optimized to reduce rebound torque and withstand repeated compression cycles in harsh marine conditions.

How does the HC4645H improve steering performance on my outboard boat?

The HC4645H provides a direct, reliable hydraulic interface between helm and outboard to deliver smooth, positive steering response. Its 197.3 mm stroke and 409.7 kgf output force help maintain control across typical load conditions without excessive play.

• 117 cc hydraulic volume for predictable flow and helm feel
• 32 mm tube I.D. and 16 mm rod I.D. for balanced strength and fluid capacity
• 409.7 kgf output force to handle loads from common outboards up to 150HP
• 197.3 mm stroke to accommodate typical steering arm travel

What features protect the cylinder from marine wear and rebound torque?

The HC4645H uses corrosion-resistant aluminum alloy construction and ORB stainless fittings to limit seawater damage and simplify hose routing. A built-in two-way lock valve eliminates rebound torque during torsion, preventing unwanted kick-back at the helm.

• High-density aluminum alloy resists seawater erosion for longer service life
• Positionable stainless-steel ORB fittings let you route hoses neatly and securely
• Two-way locking valve reduces rebound and improves safety under load
• Advanced crush resistance reduces permanent deformation from repeated compression

How do I install and match this cylinder to my boat and outboard?

The HC4645H is a front-mount cylinder designed for installations where the steering cylinder mounts underneath the steering arm, commonly on Yamaha-style setups. It ships with two hoses to simplify plumbing; confirm mounting points, stroke needs, and engine compatibility before installation.

• Intended for single-outboard boats rated up to 150HP
• Front-mount configuration fits under steering arm arrangements
• Includes 2 hoses for immediate hookup and easier replacement
• Measure steering-arm geometry to verify the 197.3 mm stroke suits your application

Who is this cylinder for? The VEVOR HC4645H is geared toward boat owners, mechanics, and small commercial operators who need a robust, front-mount hydraulic steering solution for single-outboard craft up to 150HP. It's well suited for anglers, center-console owners, and anyone seeking a corrosion-resistant cylinder with strong crush resistance, reliable anti-rebound performance, and hose-routing flexibility. Always consult your boat and outboard manufacturer specifications and a qualified marine technician to confirm compatibility and ensure safe installation.
