F-Ribs And Sibs - Inflatable Boat Community

I'm going to add a water discharge to my SIB transom to run my bilge to and am wondering what you all use for a sealant. I thought about 3M 5200, the gold standard for boats, but not sure if that is the way to go or not. While I don't intend to ever need to remove it before the seams fly apart on the boat if I ever did have to remove it then it would be virtually impossible.

Any sealant would work,but a proper marine sealant would be best. Over here the standard is sikaflex.

Funny, when I look on Amazon for Sikaflex it shows Sikaflex and 3 results down the 3M 5200 . Thank you! The 5200 is marine sealant as well, I do like that the 3M comes in a smaller container that doesn't require a caulk gun for smaller jobs (as well as the caulk gun version).

was told silkafix is an adhesive and not to use it . bought gp200 seems to be the one that covers the lot
