Went out last week in the arfo, was sitting there on the anchor when we noticed water coming in the scuppers, started up,bilge pump on pulled the anchor headed back to hillarys

Week before I'd  put on a self bailer bung so I thought to myself had the tube come off. Went down on the back board could feel the rubber bit had come off replaced it with a normal bung and went back fishing. It was filling up with water like Id left the bung out. This could have ended differently had it have been dark! Be aware of these things if using them. They may need a steel hose clip or some thimg to hold them on.
