The Super Ultimate AK and Super Ultimate AK DELUXE systems, provide you with the largest and latest Ultimate steering fins for your Yamaha model year 2015 through 2018 24ft. twin-engine or 2017 through 2018 21ft. twin-engine articulating-keel boat.

This system is based on our most popular Ultimate steering system and our Magnum AK system. This system is an adjustable, selectable, spring-loaded steering system with the second tie-rod included to balance out your original factory steering system.

We also redesigned the top portion of the fin, making it larger to provide even more slow speed control while the boat is operating around the dock or in slow no-wake mode traveling in forward and reverse.

This increase in the fin surface only comes into play when the boat is operating in the water at slow speed.  Once the boat is up on the plane the top portion of the fin is not in contact with the water due to the normal attitude of the hull when on plane.

This system takes the boat to a new level of steering control.  It addresses all areas of your boat's handling and allows you to choose from a wide variety of steering enhancement settings, starting at idle speeds to high speed and even in off-power situations or water sport activities.  Great for guest operators also.

This system will transform your twin-engine articulating keel jet boat steering response from sluggish to amazing.


Super Ultimate AK DELUXE Features


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


The DELUXE upgrade adds inside top fins and a planing surface to the existing Ultimate AK and Super Ultimate 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.


The Super Ultimate AK systems are also compatible with the new Mega Fang Plus upgrade for smooth and easy steering at wide-open throttle during sharp turns to improve reverse thrust and stopping power in reverse as well as better reverse steering control.

Or you may choose more features at less cost and upgrade with our Mega Fang Plus system.  Remember NO other steering system can come close to the steering improvements you will receive with this system. 

Here is a description from a customer who had another system on his boat and then tried this one with the mega fang plus upgrade.
