This is the culprit that made for an amazingly tall and short surf wave as my bilge filled with water.

The port was a partial pullout from battling a glued in factory fitting that didn't give up easily.

Repaired once with 3m 4200 and failed after a couple days.

Repaired again with rubber cement and although it looked better, failed almost immediately. The grimy looking stuff is the leftover cement and it just peels right off with little resistance.

Is there any glue out there that can hold the port into the bag again??
