Mayfair's "NEW" Modular Wing Plate Add-On Hydraulic Steering Systems

Mayfair by Hardin Marines Innovation has once again brought to the performance powerboat and recreational sport boat industry a steering revelation with its all new modular wing plate steering systems. By using 21st century manufacturing techniques Mayfair by Hardin Marine has developed a superior 316L Stainless modular wing plate steering mount. This wing plate steering mount design incorporates dual side links and a single rear load cap that bolt together forming a strong bridge like cradle that provides the ability to mount the wing plate to the boats key attachment points. The rear load cap captures the outdrives rear end cap while the side links attach to the outdrives four mounting points at the Gimbal housing. This arrangement gives additional support for even tighter, firmer steering control.  Best of all there is no disassembly of your outdrives rear end cap (Voids Factory Warranties) and these new systems fit all generations of Bravo outdrives including the new "Slope Back" style.  Generally speaking, it is recommended to use external power steering on boats which run in excess of 70 MPH, however there are some boats that run 60 MPH that would benefit from the use of external power steering. 

The Mayfair Add-On Hydraulic Steering System includes:

• (1) 137-9267 - Dual Cylinder Hose Kit
• (2) 137-9259 - Mayfair Steering Ram Assembly 9" Stroke
• (2) 137-9443 - Mayfair Gen II Hydraulic Steering Wing Plate

As you will see in the following pages there has never been more option, more choices, and more ways to save than ever before on the purchase of a new hydraulic steering system. We are constantly asked which system is "best" and"why"?  Well, all of the systems listed here are of the very best in quality. What separates them in many cases is very minor features such as fitment options or how complete the kit is. Some manufactures provide the bare minimum and save through the use of possibly rubber lines, aluminum components instead of stainless steel, etc. At the end of the day what makes a great steering system is "Value" all of these systems will meet your needs some will just leave a big chunk of your money ($$$$) still in your wallet. Compare and save "NO ONE" can save you more money on your new steering system than we can,try us the answers are crystal clear.

Note: It is required to use either the Brazilian steering manifold (135-1040)  or Saginaw shuttle valve fittings (135-1070) which are sold separately.
