My boat has two screw in hatches that were originaly sealed by o rings. Well the o ring have worn out and are long gone. I have searched the net and can’t find replacements. Does anyone know where I can find some new ones? They need to be 8" in diameter and as best as I can remember about 1/8" thick.
The big rain last night put a lot of water in the bilge, the pump came on, the float switch stuck, both batteries are dead.
Buy the diameter you need, use a new razor blade to square the ends after you size the diameter (just lay it out in the groove)use quick set super glue.
