Want to keep the water from splashing up through the holes on your YuPIK, Cuda, Big Tuna, Coosa HD or Bite Series kayak? This kit includes eight scupper plugs. Although there are eleven total scupper holes on the YuPIK, only eight of them require plugging to prevent water from coming up through the holes (the other five are under the seat pan and allow the kayak to self-bail when navigating rain, soggy paddle strokes and other reasons).
