I just bought a 26S and my cockpit drain isn't draining. I tried the following things. Forcing water up through the bottom hole and down through the drain hole, pushed a drain brush through the drain hole but is will only go half way, a leaf blower. Next i am going to try my shop vac. I keep the boat an hour away so i can't just go in the back yard and try stuff. Should i be able to push something down the drain hole? Does it curve?
