  • 1965 Johnson Tri-Hull restore!

    Well this winter I decided to go through my boat, it has a soft spot in the floor. So today I yanked the motor off and pulled the cap off the transom!! OUCH! This hole I created with my finger!!



    The other side!





    So question is about removing the cap. Its glassed on all the way around on the inside. So do I just take a cut off wheel and cut right through the joiner piece of fiberglass?

    Welcome to iBoats!
    Do NOT CUT!!!
    Does your boat have a Bump Rail?? If so remove the Rubber and you will see that your boat's top cap is held to the hull by a series of rivets or screws. Hundreds of em. Remove all of them and you should be able to remove the top of your boat. There MAY be some adhesive holding the two halves together that MAY need to be cut free but it should be minimal. Post some more pics of the exterior of your boat to confirm how your boat is constructed.

    I'm just sayin...

      Yes it has a rub rail. And I just removed it. But when I look on the inside there is what looks like the top is glassed to the bottom. I'll go take some pics.

        Rub rail removed.



        Where cap meets hull!! This is what it looks like all the way around.

          Wow, that's a new one on me. We will have to let the EXPERTS give you advice on that one. I have not had experience with that kind of hull. Can you get a putty knife or anything in between the layers???

            Maybe a putty knife after I cut that fiberglass.

                  Got the carpet out tonight, dang the floor is just as bad, I could see it lifting as I was tearing up the carpet.

                  So I need to start thinking of materials, I don't really want to use Epoxy due to cost. Is regular fiberglass resin ok, I think its called poly? Maybe?

                    I have seen two of those style of boats out my way. The two halves are glued together all the way around with a gasket water sealer caulking. You can seperate the two halves by using a wide flat air hammer chissel and starting from the stern on either side and carefully workinig your way around. Another way would require two people and a long band saw blade. Wearing gloves youu saw back and fourth along the center the same as before. Not too difficult just time consuming.

                      Ouch! That's gona suck! Oh well. Maybe I can work around the whole boat with a thin piece of steel and a hammer?

                            Now a Sawzaw is a mans trump tool. I was going to sugest using that but if you are not comfortable with using one you can create way more damage then good using it to save time. Great job seperating your cap, not too difficult and believe me, yours was easier then mine.

                              Ya, I've used tools enough to know what it can do, and how to control it, it was hard to keep it going straight, I only went off once and cut slightly below the lip, but not biggie to fix. It took me the evining to get it off by myself. Now to recruit a few guys to lift the cap around the house to the back yard while I work on the hull.

                              Honestly I don't now how else I would of got it off, that glue was freakin strong!!! And very hard as well, not sure what else would cut it.
