This is a small, limited-run part with one job: holding a K4C electric fin on an inflatable boat’s transom. It suits anyone who already has the K4C remote-steering eFin, or plans to buy one, and wants to mount it on a boat with a transom instead of a kayak or SUP fin box.
Specs at a glance
- Fits: K4C electric fin
- Mounting: transom of an inflatable boat
- Build: custom made, limited production run
Good to know
- Check that your motor is the K4C model before ordering, since the adapter is listed for the K4C electric fin specifically.
- This listing is the adapter only, so the eFin motor and battery are a separate purchase if you don’t already own them.
KayakDIY take: Small mounting parts like this are often what make a motor setup actually work on a boat it wasn’t designed for. For more options, see my best kayak motors guide.
