Ihave one adapter on my starboard inflatable and another one my starboard touring hard board. Love my boost motor. Im 67 and still paddleboarding when I get a chance!

It was a bit tight on my Starboard touring, but I managed to get it in the groove and I don't suspect it will ever come out! Love my boost motor!
