MaXtek Marine Hydraulic Steering Cylinder 150hp delivers precise, dependable helm control for boats fitted with outboards up to 150hp. Built to handle both 2-stroke and 4-stroke engines, this cylinder stands up to the torque and weight of modern outboards with a robust, purpose-built design. The Bullhorn Mount keeps a compact footprint in tight engine wells while delivering smooth, balanced steering from lock to lock.

Why this cylinder stands out

• Balanced cylinder — equal turns lock to lock: Consistent steering effort through the full travel, reducing helm strain and delivering predictable response in rough seas.
• Rugged construction: Stainless steel shaft with hard chrome plating for long-wearing performance, paired with an anodized aluminium tube and bullhorns to resist corrosion in marine environments.
• Secure, durable fasteners: Stainless steel locknuts that stay tight under vibration and salt exposure for reliable operation over time.
• Compact, marine-friendly footprint: Designed to fit limited engine wells without sacrificing power or leverage, ideal for boats with tight engine bays.
• Universal mounting with a Yamaha option: Standard mounting bracket fits nearly all outboards, with an adapter plate available for Yamaha F30–F70 to optimize fitment.
• Proven, purpose-built for 150hp and below: Rigorous testing and over-engineered components ensure this cylinder can handle the demands of modern 4-stroke setups.
• Direct-from-supplier availability: This item ships directly from our suppliers, with clear part identification (code ST3016-1 J -22.02.22) to support easy ordering and replacement.

Ideal use cases

• Center consoles and small fishing boats that rely on reliable hydraulic steering for up to 150hp outboards.
• Boat owners upgrading or replacing aging steering gear who want a robust, torque-ready solution that survives salt spray and repeated helm adjustments.
• _rig-and-restore projects_ where space is at a premium and a balanced, lock-to-lock system improves control in variable conditions.

Compatibility and installation notes

• Compatible with all 2-stroke and 4-stroke outboard engines ≤150hp.
• Standard mounting bracket supports a wide range of outboards; use the Yamaha F30–F70 adapter plate if your model requires a precise fit.
• Installation should consider secure mounting, proper hydraulic connections, and a bleed/prime of the system to ensure smooth operation from the first use.

Materials and durability

The combination of a stainless steel shaft with hard chrome plating, an anodized aluminium tube, and bullhorn components delivers corrosion resistance and longevity in saltwater environments, making this cylinder a reliable long-term steering solution for recreational and light commercial use.

Maintenance tips for peak performance

• Periodically inspect mounting hardware and seals for signs of wear or salt buildup; tighten locknuts to spec as needed.
• Flush hydraulic lines with fresh water after saltwater use and re-check for leaks or soft seals.
• Follow the manufacturer’s guidance for hydraulic fluid compatibility and periodic system bleed to maintain smooth lock-to-lock action.
