    Default ** How to mount IMCO SS TANKS?**

    What is the best way to mount these brackets to my tunnels? would a carriage bolt from the bottom be a bad idea? bottom only looks like about 1/2" thick

    you can do it that way or glass or epoxy in some wood with the bolt through the wood. Dont really like drilling holes through my boat though, but thats how i had to do my foot throttle.

    Heres a thought, countersink a stringer washer and use a flat top SS bolt, but Epoxy the bolt and stringer washer down, like you would do at the Intake, clean it up and you will not get a leak from the through hull bolts!
    I think this is what the guys above are getting at, but the seagoing putty would make it closer to "Bullet proof" than Silicone.

    Didnt somebody do an article in HB on just how to do this?
    Oct 2005 issue I think.

    put some studs in a piece of aluminum then glass them down.

    If you want a copy of that article PM me and I'll email it

    I saw that article. Depending on the tanks used some boats don't have enough clearance
    to get the tank and bracket into place with the bolts sticking up. My old Kachina was like
    that and I used the method Todd describes above. Didn't use epoxy though. Even though
    the hull was only 1/4" thick in that area, the bolts and stringer washers used in conunction
    with silicone did the trick. Used it for a lot of years like that, ran the boat in some really
    crappy water at times and they never came loose.

    The gullwing I bought was set up the same way when I got it. Although the tanks
    weren't installed when I picked the boat up, just used the same holes and did it
    again when it was re-rigged. This boat had room to get the tanks in the way it's described
    in the article, but the holes were already in the boat. You can see where "the squeeze" is
    (white silicone). It kinda forms it's own little gasket.

    I don't have a tunnel, but I used nut-serts with studs in the plywood floor. My gunnels were so low that I had to put the brackets on the tanks then locate them, put in the studs, then washers and nuts. I had to replace the floors with 1/2" plywood just to squeeze them in. Maybe you could use a thin piece of plywood for the nut-serts then glass it in. If you go this route make sure not to drive the stud through your hull! Maybe dab epoxy in the back to stop the stud.

    X 2 On the bedding epoxy, helps keep stuff in place, eliminating chance of leakage. The Imco brackets are about as low profile, as you can get.
