Mercury - STEERING CYL KIT - 8M0118141

When it comes to smooth, precise handling, the steering cylinder plays a bigger role than most boaters realize. The Mercury Marine Steering Cylinder Kit - 8M0118141 delivers the kind of control and reliability that keeps you confidently at the helm, whether you’re backing into a tight slip or running wide open across open water.

Built specifically for select Mercury outboards, this OEM cylinder is designed to handle the constant flex, torque, and vibration that comes with serious time on the water. Its corrosion-resistant housing stands up to salt spray, UV exposure, and rough conditions, while the internal piston glides smoothly across its polished surface — reducing steering effort and ensuring consistent performance. High-quality seals lock in hydraulic fluid and block out contaminants, helping the entire system hold pressure longer and run cleaner over time.

What sets this cylinder apart:

• Direct fit for select Mercury outboards — no modifying or guesswork
• Corrosion-resistant exterior stands up to saltwater, UV, and vibration
• Polished internal surfaces deliver smooth, predictable steering response
• Premium seals prevent leaks and keep contaminants out

Best applications:

1. Replacing worn or leaking steering cylinders to restore smooth, responsive handling
2. Upgrading to maintain reliable steering performance in high-hour or saltwater environments
3. Ensuring safe, predictable steering in both recreational and commercial applications

A boat’s handling starts at the helm — and with this Mercury steering cylinder kit, you get the kind of control that makes every trip feel dialed-in and predictable.
