I ordered a normal fin box and cut a section out if it out to make it compatible with the subnado mount. (See my video). Review: Fun!! - Works great!! I did have to fine tune it ro match my board so it would easily fit by taking a utility knife to the plastic tip of this bracket & give it a small chamfer which took about 20 seconds. Kids & I rode it up & down the lake and had a blast all weekend long. ## Features - 【SLIDE-IN FIN BOX COMPATIBILITY】 Designed for paddle boards with a compatible slide-in fin box. Please confirm your board’s fin box type before purchase, as this mount is not intended for US fin box systems. - 【PADDLE BOARD PROPULSION SETUP】 Use with the Subnado underwater scooter to create an auxiliary propulsion setup for compatible SUP boards, inflatable paddle boards, hard paddle boards, and other light watercraft. - 【QUICK-RELEASE INSTALLATION】 Confirm that the quick-release clamp is secure, pull out the latch, insert the mount into the base slot, align it properly, and reinsert the latch to lock the mount in place. - 【ALIGN, PRESS & CHECK】 Align the Subnado with the mounting base and press it down until it clicks into place. Check that the scooter is firmly attached and stable before entering the water. - 【WARRANTY TERMS】Subnado sea scooter comes with a warranty for 6 months to 1 year from the date of purchase.
