Details

COBRA SUPER MAGNUM AK Series steering was specially designed for the 21 and 24 foot Articulating Keel Yamaha Jet Boats ONLY.  For other Yamaha Jet Boats, we recommend the Cobra SUPER ULTIMATE Steering system.

The system was specifically designed to provide a balanced, clean looking, and effective steering enhancement for your model year 2015 through 2018 Yamaha 21 and 24-foot jet boat with an articulating keel.  2019 and newer models require the Magnum AK-19 Steering System.

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.

SUPER FINS

This steering system comes as our latest SUPER MAGNUM version.  The Super Magnum fins have additional influence at low speed and no-wake mode for more control in both forward and reverse.  This is accomplished by adding more surface area to the top portion of the fins only.  Simply put, when the boat is up on plane, even if your fins are in the full-time mode the top of the fins are above the water and only the lower portion of the fins are making contact with the water providing steering assistance.

By increasing the surface area on top and the back of the fins, once the boat comes off-plane the hull sits lower in the water and the entire fin is now making contact with the water allowing the additional surface area at the top of the fin to apply the additional steering influence to the boat without increasing the draft of the fins.  This is always important, especially on a single-engine boat as the pump is the lowest point of the hull. 

Super Magnum AK DELUXE Features

The New Super Magnum AK DELUXE steering package is now being offered as both an upgrade to new Super Magnum AK package orders, and as a very affordable upgrade package for previous Magnum AK and Super Magnum AK steering systems.

The DELUXE upgrade adds inside top fins and a planing surface to the existing Magnum AK and Super Magnum AK steering systems.  The top fins are positioned so that they do not come into play until the boat is off-plane and operating at slow speeds.  The position of the hull when off-plane places these extra fins in the water, and automatically out of the water again once the boat is on-plane.

This automatic increase in fin influence follows suit with the Super Fins above, as both are designed to add more steering influence when needed and automatically change that influence when the boat is on-plane.  The combination of the side fins and the top fins when driving slowly in forward or reverse, driving in minimum or no-wake zones, heavy traffic, wind, waves, or strong currents, docking, or picking up water sports participants from the water provides additional steering influence and makes performing those activities much more accurate, predictable, and responsive.

The additional planing surfaces created by the enlarged side force stabilizer brackets are reported to provide very fast holeshots and a smoother ride in choppy conditions, as well as a cleaner wake behind the boat at planing speed.

COBRA AK FANGS

COBRA AK MEGA FANG PLUS

Or, you can now max it out with the new MAGNUM AK MEGA FANG PLUS System.  This system gives you the most reverse control from TWO MEGA FANG PLUS fins mounted on each nozzle to direct the flow of water exiting the reverse chamber of the nozzle, providing maximum steering control when in reverse, and improving the stopping ability of your jet boat when you need it.  Also with the twin FANGs per nozzle MEGA FANG PLUS setup, you will experience more power steering at speed and super steering response at all speeds, even at the fastest speeds where the keel tries to override the steering input on stock boats.  The MEGA FANG PLUS system provides the MAXIMUM EFFECT in forward and reverse, high speed or slow speed when coupled with the Super MAGNUM AK DELUXE Series and the Super MAGNUM AK Series steering systems.
