unclog
Hi Jim,I would try using the pressure from a garden hose. The outlet is below the waterline on the centerline (keel), about three feet from the transom. The second attempt to unclog would be from under the boat with the garden hose to reverse the pressure/push. Be very careful if you push something down the pipes. The original was that accordion flex pipe. It will easily be damaged. You can see the pipe and through hole by looking in the stern under the deck. Under the waterline work can create MAJOR safety issues. Contact a boat yard, if you are not sure about what you are doing.Good luck.Mark
