New for 2019, our latest Super Steering Fins for all Ultimate and Magnum systems, past and present.

Capable of being upgraded on your existing system!

Specially designed fins that increase the steering influence above and beyond the regular Ultimate or Magnum fins capabilities while operating your boat in slow and no wake speeds to provide even more slow speed forward and reverse steering control .

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

When the boat is on plane, only the fins 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 fins to make contact with the water, joining forces with the lower portion of the fins to increase the slow speed influence by using the entire surface area of the fin.

Simple and very effective.

The Super Steering Fins may be swapped with any existing fins that are on your boat.  Super Magnum fins can be used in place of any Magnum system fins currently in use.  Likewise, the Super Ultimate can replace any Ultimate system fins currently in use.

This way  a customer wishing to upgrade their system may  purchase the Super Steering Fins separately with no need to change the entire system to obtain the latest upgrade.

So simply put, more slow speed forward and reverse control while maintaining the same excellent high speed control you are accustomed to from your Cobra Jet Steering system, just by changing the fins to the latest design. 

For new customers we will offer the new Super Steering Fin version for ALL the various Ultimate and Magnum systems in an effort to provide you with the most options and the best selection of steering for your Yamaha jet boat.
