Water infiltration

[boomy]

I have a 91 Boomerang with some water infiltration, and I believe it's seeping in from the under fin. So does anybody know what type gasket is required between the hull and fin???

Im pretty sure its just marine silicon that seals them. I hers its a real pain to remove the fin as its bolted threw the hull to a large plate on the sinde to add stability.

You could srat with removing the screws and resealing that, then seal around the frame of the fins and see if that stops the leak.
