    Hello everyone,
    I am building a small wood boat with a Yamaha jetski engine and pump drive.
    I cut the bottom of the jetski hull out to fit into the bottom of my boat. I am trying to find a good bonding material that will help seal and bond the fiberglass jetski hull to the bottom of my plywood boat. It will be screwed in place also so the material will be more of a sealer than a bonder. I am looking for stuff that is like what the jetski manufactures use to bond their hulls together. If any of you have seen this stuff, it is REAL strong, but stays semi rigid. It does not dry hard and brittle, but it is harder than just window caulk.
    Anyone got any suggestions on what I can use and where to get it?
    Thanks, Tony

    My guess would be a 3M Polyurethane Adhesive such as 3M 560 ( Scotch-Seal) or similar.

    We use Cray Valley "Thixo Iso UPE1254" bonding paste to join GRP decks to hulls. Immensely strong join when cured.

    Epoxy, epoxy, epoxy. You don't want a sealant, you want to bond it solidly. Epoxy and fabric, preferably biax.
