T-H Marine Steer Stop Outboard Hydraulic Steering Lock Set - 4"

The T-H Marine Steer Stop Outboard Hydraulic Steering Lock Set—4" is a purpose-built steering stabilization device designed to keep outboard motors with hydraulic steering centered and locked in place during trailering. T-H Marine engineered the original steering stop for outboard motors and has refined the design to outperform competitive alternatives on the market. This 4-inch hydraulic steering lock prevents the motor from wandering or swinging side-to-side as the boat moves along the highway, reducing stress on the steering system and protecting against accidental engagement during transport.

The device works by locking the steering column in a centered position, eliminating the lateral movement that can occur with hydraulic steering systems on trailers. The 4-inch dimension refers to the steering lock's effective range, making it compatible with standard outboard motor hydraulic steering columns. Installation is straightforward and requires no modifications to the motor or steering apparatus. The compact design—weighing just 0.45 pounds and measuring 5 x 2 x 7 inches—fits easily in any tackle box or boat locker, making it convenient to deploy before every tow.

This steering lock is essential for any boater who regularly trailers an outboard-equipped vessel, from weekend anglers running to the nearest fishing hole to serious offshore crews managing long-distance hauls. Uncontrolled steering movement during transit can cause premature wear on hydraulic hoses, steering cylinders, and rams—repairs that far exceed the cost of preventive gear. By keeping the steering centered and stationary, the Steer Stop reduces the physical stress on hydraulic components and ensures your motor arrives at the ramp in the same condition it left home.
