As shown in the photo, this is a replacement "LOWER" bracket only for the new adjustable Yamaha Blaster Bilge Pump brackets. This is sold separately from the upper mount as a replacement if you're upgrading to a dual pump system from a single pump system and does not include the upper mounting bracket. Hardware as shown is included with the lower bracket. This bracket will fit the upper bracket without issues, there is no difference in the design of the mounting slots so the single and the dual are interchangeable.
All of the hardware is 18-8 stainless steel for maximum corrosion resistance, the brackets are manufactured using 5052 aircraft grade aluminum sheet and precision fabricated to precise tolerances. The unique design has high quality all stainless "pem" nuts that are pressed into the upper bracket so there are no loose nuts to hold for installation, all you need is an allen wrench ! The slots in the lower brackets allow for plenty of adjustment for virtually any circumstance. These all new Yamaha Blaster Bilge Pump brackets are anodized in a bright blue to give your ski a custom and professional look and protect the bracket from corrosion and we proudly laser engrave our name on them so you're friends (and foes) will know you've bought the best !
