    I'm building a small wooden jet boat from a cannibalized jet ski. The nice thing about the particular ski I used is that the jet pump housing is a bolted-in aluminum casting instead of the common molded-into-the-hull fiberglass housing.

    So... The seal material that lines the interface surface between the pump and the hull is in rough shape. I'd like to replace it. Can anyone recommend a good material? Is there some marine-grade weather stripping I could use? It would have to be pretty wide. I would be looking for something that can stand up to salt water. I've attached a couple pictures of the pump and seal. The seal will press up against a planed white oak board, coated with west systems epoxy.

    Have you asked the parts dept of the jet-ski manufacturer? They might have the gasket.

    They stopped making jet skis about 13 years ago. I have found suppliers for many replacement parts, but not for this particular seal. For all I know, one of the previous owners replaced it with some DIY solution. I considered using automotive weatherstripping.

    What you're looking for is closed cell polyurethane, neoprene or sponge rubber sheeting. It's sold in rolls, though I think you can get small quantities for some manufactures.

    acehose.com
    star-seals.com
    metrogasket.com

    are a few places you can find some . . .
