Cobra Super Ultimate AK-19 and new Super Ultimate AK-19 DELUXE steering for 2019 and newer Yamaha Single Engine Jet Boats

Now available:

The Super Ultimate AK-19 Steering System designed for the 2019 and newer Yamaha single-engine jet boats.  This system offers all the features and benefits of the original Ultimate steering with a wider and more effective stance to be compatible with the updated nozzle designs since 2019. Fully adjustable, selectable, and spring-loaded this system is built from the same tempered aluminum for strength and effectiveness with a low profile.

DELUXE Side Force Stabilizer Upgrade

The Cobra Super Ultimate AK-19 DELUXE Steering System adds a planing surface to the side force stabilizer.  You can see the difference between the stabilizers of the two versions and see the DELUXE version in it's installed position in the second.  This planing surface can provide benefits such as faster hole-shots and a smoother ride in choppy conditions.  It also sheilds the jet water exiting the nozzle from water rising up from the ride plate under the pump so as to reduce its deflection of the jet water and helps to keep the water behind the boat cleaner with less spray for water sport activities.

SUPER FINS

This steering system also includes our latest SUPER ULTIMATE fins.  The Super Ultimate 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. 

Our designs do all the work, you have all the fun.
