Cobra SUPER MAGNUM AK Steering for Twin Engine 21ft and 24ft Articulating Keel Yamaha Jet Boats
Cobra Venom Magnum AK Series

The Cobra Super MAGNUM AK system for twin-engine Yamaha jet boats with the Articulating Keel was specifically designed to address the needs of these particular boats.  This system fits model years 2015 - 2018.  Model year 2019 requires the Magnum AK-19 system.

WHAT we did and WHY:  Your AK jet boat has a very large keel down the center of the hull.  This keel resists turning and the faster the boat travels the more it wants to go straight!

Yamaha added a rudder to the back of this keel in an effort to deal with this tendency.    This added keel puts more stress on the steering components (NOZZLE, CABLE, HELM, etc.) and more force was needed to turn the steering wheel at speed.  They added a rack and pinion steering to this boat to make the wheel easier to turn by its operator.  Unfortunately, the turning ratio was greatly increased from a 1/4 turn for a full right or left to a 1/2 turn of the wheel to accomplish the same thing.

The MAGNUM AK system addresses these issues and more.  After all, if you were happy with the handling and steering of the boat you would not be here looking to improve it.

Our Magnum AK system adds two extra fins to the steering system.  These are NOT just slow-speed part-time fins, our system works ALL THE TIME because your boat needs more assistance at ALL speeds.  The fins in conjunction with the factory rudder form a "V" configuration to give an instant response at all speeds cleanly, effectively and predictably.  We also went to great lengths to build a very heavy duty stainless steel tie rod to balance out the work being performed by the nozzles, steering cables, and helm.  This additional tie rod allows your system to push on the steering nozzles and fins AND pull on them, both at the same time.  It also balances out the workload to both sides of the steering helm, nozzles, and the steering cables, and also adds redundancy to your system.  This special system just makes sense.  

We also made a special upgrade called the Magnum AK FANGS for even better reverse, plus a power steering effect.  Check them out below.

Cobra Viper

Our newest model-specific CJS VIPER steering system is specially designed for use on the Yamaha 19-foot single-engine jet boats.

Between the fins, we added a planing surface for quicker hole shots, easier planing, and more hull stability in rough conditions.

NEW Cobra MEGA FANGS PLUS for Yamaha
Cobra Venom EZ-Locks

MEGA FANGS PLUS are our latest steering system Upgrade.  These specially designed fins mount just below the nozzle using a special base plate that places the fins next to the reverse water exit under the boat.  These MEGA FANGS PLUS direct the reverse thrust to push in a more controlled manner, providing more reverse response in all directions.  This gives you a REAL REVERSE for much more predictable control and confidence when backing in tight places or turning in reverse.  The MEGA FANGS PLUS also add a POWER STEERING effect to your steering system by placing part of the MEGA FANGS PLUS fins forward of the nozzle pivot point, thus using the forward momentum to help turn the steering nozzles and fins with ease at all speeds.

The MEGA FANGS PLUS are compatible with the ULTIMATE, MAGNUM 16X, and MAGNUM AK Steering Systems from Cobra Jet Steering, as well as any SUPER version of those systems.  They are NOT COMPATIBLE with the CJS VIPER Steering System for the single-engine rudder equipped jet boats.  However, they can be added to the non-rudder NK and NK II versions to make up for not having a rudder.
