COBRA SUPER MAGNUM AK-19 steering was specially designed to accommodate the Yamaha nozzle and reverse bucket redesigns for the 2019 model year.  We have completed the changes necessary to provide you with the Magnum AK steering for more control at all speeds from docking to wide open and water sports activities.

Having a keel on the bottom of a jet boat has a tendency to make the boat resist responding instantly to steering input, even with the addition of the rudder at the end of the keel.  This unfavorable tendency increases as the speed of the boat increases.

Our model specific steering system addresses this lack of response to the helm.  It is also adjustable to allow you to set the correct amount of influence for your personal preference.

Our "V" configuration of steering influence compliments the factory rudder with two of our SUPER MAGNUM steering fins attached to the outside of each nozzle to greatly improve your boat's handling and your boating experience.

We also improved on the original factory design by adding a second tie-rod to the left side nozzle for a balanced and even distribution of the workload that both pushes and pulls the rudder from either side to prevent uneven wear on the right side nozzle and steering cable.  To view the easy bolt-on installation process, see the video included with the product pictures above.


New Super Magnum AK-19 steering for Twin Engine 2019 Yamaha jet boats are specially designed fins that increase the steering influence above and beyond the regular Magnum fins capabilities while operating your boat off plane to provide even more slow speed, forward and reverse steering control.

This is accomplished by increasing the upper portion of the fin without disturbing the original design below the nozzle, as that area effects the high-speed influence.

When the boat is on plane, only the fin's surface located below the nozzle is in contact with the water.

Once the boat comes off plane the hull sits much lower in the water.  This allows the upper portion of the fin to make contact with the water joining forces with the lower portion of the fin thus increasing the slow speed influence by utilizing the combined surface area of the entire fin.

Simple and very effective.


And you can also add our new COBRA FANGS upgrade for the SUPER MAGNUM AK 19-Series steering system for added reverse control and a power steering effect.
