      Hydraulic Boat Steering: The Basics

      Hydraulic boat steering systems provides you more control over your system which allows for easy steering out on the water. This makes it easier to pass other boats, avoid hazards, and turn your vessel around.

      These kind of marine steering controls make controlling your vessel a breeze. A power steering system is perfect for large and high speed boats where precision and maneuverability are key.

      A boat’s hydraulic steering system utilizes hoses, a helm pump, and hydraulic steering cylinders.

      Hydraulic boat steering depend on pressurization for efficient operation. When you begin to turning the steering wheel, a helm pumps hydraulic steering fluid through the lines to the ram. This pushes or pulls the rudder, outboard or sterndrive in the desired direction.

      Modern hydraulic systems feature variable assist and responsive feedback mechanism for personalized steering experiences. One of the greatest benefits from this type of hydraulic steering system is the massive reduction in manual effort the captain needs to exert control. This is one the many reasons boats with high torque engines should consider a hydraulic steering system.

      Hydraulic Steering Maintenance

      Like most things, how you maintain your hydraulic steering system affects how well it performs. At the start of the season, or after 200 hours of use it is recommended to check our your steering system.

      Many boaters take their hydraulic steering system for granted until it needs repair. Generally, one of the three components usually is the source of malfunctions.

      The three main components are the hydraulic pump which features an integrated oil reservoir. The ram which connects to an outboard engine or rudder. Finally the connecting lines transmit inputs from the steering pump to the steering ram.

      Since hydraulic steering depends on hydraulic fluids, one of the key pieces of maintenance you can do is to properly maintain your fluid levels. Regular fluid replacements and system flushes are crucial to preventing cavitation, or air pockets, from forming in your system. These air pockets can cause uneven fluid displacement which can lead to sluggish or unpredictable steering responses.
