Meet the new and improved 4" Steer Stop Outboard Hydraulic Steering Lock!

New design: Now even better for locking hydraulic steering when trailering.New grip! Easier to install and remove!

T-H Marine developed the first steering stop available for outboard motors and now we've revised that design so it stands apart from imitation and performs better than any other on the market.
With our 4" Steer Stop Outboard Hydraulic Steering Lock in place, boaters can center their outboard motor equipped with hydraulic steering and keep it from wandering when trailering. Similar to the original Steer Stop, units clip onto hydraulic steering rams on either side of outboard to keep engine straight and prevent damage to motor supports. The cord then keeps units together when stowed and aids removal.
Additionally, with the new grip built into the design, it is easier than ever to install and remove the Steer Stop Outboard Hydraulic Steering Lock, saving you effort and wear and tear on your hands.

Note: the 4" Steer Stop Outboard Hydraulic Steer Lock fits Seastar and Baystar hydraulic steering.


  • Comes as a set (for each side of the steering rod)
  • Length: 4"
  • Color: Navy Blue
  • Cord: Included

4" Steer Stop Outboard Hydraulic Steering Lock

Tougher Than They Look

While considering a different brand at a much higher price, I came across these at Paradise Marine Center in Gulf Shores, AL and boy am I glad I did. After trailering our newly purchased boat back to northern Indiana, I couldn't speak any more highly of this product... very pleasantly surprised. They kept the motor centered for 900 miles of bouncy interstate, they are way tougher than you would imagine and they still look like they just came out of the package. 10 Stars if I could...

Works Great!

Great to have whenever boat is out of the water, especially during trailering or when kids what to "Speed up and down the high seas" while the boat is on the trailer ;)
