BCB, youre right, it is a no brainer to see where it is with the boat in the garage. As far as the solution thats exactly what I did. Maybe I did it wrong, any tips on how to do it properly? I waited till it was dry, used acetone to clean the old sealant away and added a generous amount of silicone glue. Then I tightened the cap as much as I could but thats where the problem lies. It seems the threading isnt pulling tight and I can just keep going with it.- Chaz
