2nd Battery Bracket for Seadoo ST3 Hull

This 2nd battery bracket will allow you to add a second larger battery. This was designed for the Fishpro Sport that uses the ST3 hull and may fit other models such as the GTX, RXT-X, Wake Pro 230, Explorer Pro.

Made in the USA from 5053 Aluminum and designed secure to factory mounting locations on the underside of the deck.

My personal setup – NOCO NLP30 with NOCO Genius GEN5X2

One side of battery from bottom to between the power terminals must 6-5/16″ or less in order to fit inside the bracket.
