Replacing the scupper drain hoses, it was rigged with wire reinforced black rubber hoses with hose clamped to NPT threads (not hose barb connections) on each end. Now I have to replace the cockpit scupper thru hulls with a 2" thru hull connections with 2" hose barb connections and add hose barb connections to the transom scupper valves. BSP what were you thinking, relying on a hose clamp to make a hose over a thread connection water tight.
