Has your bailer died, given up, bit the dust? If you have replaced the O-rings four or five times and are on your second repair kit, maybe it is time for a new bailer. Invest in a dry cockpit with a bailer that works every time.
This Laser Auto Bailer comes as a complete assembly with screws and fitting instructions. Laser Performance recommends that you add a little Sikaflex to your Laser Hull to keep it watertight.
