Power through longer water sessions with the Aqua Marina BlueDrive S Power Fin, a compact electric propulsion system built to give paddlers an extra push when wind or current starts working against them. Designed for watercraft equipped with a compatible fin box, this underwater jet provides two selectable speeds through a convenient remote control, letting you choose between a steady 4 km/h pace and a faster 6 km/h setting. The rechargeable lithium-ion battery keeps the setup portable while providing up to 60 minutes of operation, and the lightweight power fin helps add propulsion without turning your gear into a burden. With all the accessories included, the BlueDrive S gives SUP and watercraft users a practical way to conserve energy and extend their outings.
