Mine's bunged with 2 home made expanding bungs in the bow holes and a piece of perspex on the stern hole. It's got a bung in the perspex and a tiny tube running into the boat for pressure relief.
Mine's bunged with 2 home made expanding bungs in the bow holes and a piece of perspex on the stern hole. It's got a bung in the perspex and a tiny tube running into the boat for pressure relief.
The perspex on the stern is just held on with Sikaflex (equivalent to 3m 5200) and the bung is held in with the same.
The pressure relief tube is a length of silicone tube for car windscreen washers , glued through a hole down the middle of the bung then run into the boat over the transom.
