This Plug and Play Adapter allows you to change your paddleboard fin for a Bixpy Power Fin in seconds.

If you have an inflatable standup paddleboard or kayak with a slide-in fin, you can use the Paddleboard WillFit™ Adapter - Slide & Lock Fin to quickly attach the Bixpy J-1 PowerShroud™ Motor to motorize your board or kayak in seconds.

Make sure that you are getting the right Bixpy adapter for your watercraft on!

Regarding Slide & Lock fin boxes, slight alterations to the adapter may be required for rounded/nonstandard fin boxes present on various watercraft such as BOTE boards/inflatables. If you have an inflatable with a nonstandard fin box, our Inflatables - WillFit™ Adapter is a great alternative.
