  • Are Mako gunnels foam filled?

    Formulating a game plan for finally restore the 1973 22' I have. It's in rough shape and has been sitting for a solid 20 years. If you look in the bilge you can see the foam is deteriorating and crumbling. I was planning on removing all the foam under the deck when I replace the stringers but how the heck are you guys removing the foam in the gunnels? I assume it's just as crumbly as the rest of it and I don't want to leave anything untouched if it's going to fail later on down the line. Hoping this restore will last a lifetime if I want it to.

    They poured the foam in through the gunnels. I know on the 21 I tore down there was plenty of foam in there. I removed the cap to gain access there. Do not know what your plan for rebuilding is.

    Was this the 22 with the crack in the stringer inside?

        No, this is a boat my dad has had since the early 90's.

        It needs a transom, deck and stringer replacement but I wasn't planning on pulling the cap. Think I should rethink that? Would it just depend on the condition of the foam?

              What are you doing with the boat with the crack in it?

              I would say there is definitely foam. Have been helping two friends with 17s and they both have foam in the gunnels. One is way worse than the other in terms of moisture.

                What crack?

                Here's the deal, and maybe this is worthy of it's own thread. My dad has a 1973 Mako 22 with a soft deck and detoriating foam. It's in poor condition and needs a full restoration.

                My Dad's mako has the tank pulled and a new tank ready for coating. We also have access to a free 2001 Ox66 225 hp which ran when parked but has been sitting for a really long time. Lots of misc parts in boxes as well.

                Although it's going to need a lot of elbow grease I think this is the cheapest way to get us into something bigger than the 13 and 15 whalers we currently use. I'd prefer to dump money into something 26+ but 3-5k for a resto sounds a whole lot better than what used boats are going for nowadays. I just dont want to half ass it and then 5 years down the lean wish we pulled the cap to redo the foam in the gunnels. Sounds like the cap is gonna have to come off.

                    3-5 is not going to get you very far one restore. You may want to multiply that by 3. That's with you doing the work. Yes If I was pulling it down like you I would pull the cap and do it all as one.

                    You can see how much foam I removed. About 6" wide and all the way up

                        Hmmm sounds like I need to do more research. The good news is it already has a new tank so my thoughts were it's mostly going to be paint and fiberglass. Definitely interested to hear what other major costs I should expect.

                            The deck is going to need to be redone if it is soft, which materials will cost you a bit there. How is the transom?

                            Do you have all the rigging, steering, and electrical for the boat and motor?

                            Didn't you have a Mako that had an issue with it as well or am I thinking of someone else?
