T-H Marine SS-3 4 Inch Steer Stop Hydraulic Steering Lock, Pair - Fits Seastar and Baystar Systems

The T-H Marine SS-3 4 Inch Steer Stop is a hydraulic steering lock sold as a pair, designed to hold an outboard motor centered and stable while a boat is being trailered. Each steer stop snaps onto the hydraulic steering cylinder rod, restricting movement of the outboard so the motor cannot swing or bounce against its mounting during transport. This helps protect the outboard, the steering system, and the trailer from impact damage caused by road vibration and turns.

The SS-3 is built to fit most hydraulic steering cylinder rods, including Seastar and Baystar steering systems, making it a straightforward add-on for boat owners running these common setups. The steer stop uses a cylindrical, snap-on design with an enhanced grip surface, allowing it to be installed or removed by hand without tools, even in cold conditions. The two steer stops are connected by an integrated cord so the pair stays together in storage between trailering trips, reducing the chance of losing one half of the set.

Constructed of durable plastic, the SS-3 is intended for repeated use over the life of the boat and steering system. It installs directly onto the existing steering hardware and is removed before the boat is launched, then reinstalled for the next tow. The compact 4 x 2 x 4 inch size keeps it out of the way while still providing a firm mechanical stop against motor movement.
