These boats were designed to get splashed in the cockpit. The scupper is a neat feature in the design. Just replace it, and move on. If your safety lanyard keeps falling off the post, are you gonna use duct tape to hold it on? If the hose fails also like the scooper it will allow water into your hull and possibly sink. Good chance if the end rotted and fell off it's leaking water inside you'll never notice, till it's too late. That's why the scupper is at the end and not inside the boat somewhere. So it stops water before it can go inside.
