Zodiac Dinghy Transom Repair

The process taken to Refit the Zodiac Transom back to the PVC tubes.

1. Zodiac Transom and transom fittings which were removed by hot air gun.

2. Transom prior to clean-up. The single part Hypalon Adhesive is used later to prime the wood of the transom prior to final fixing with PVC two part adhesive.

3. Removing old glue from Zodiac inflatable with power tool.

4. Removing rowlocks (which were also coming un-stuck) with hot air gun.

5. Rowlock removed.

6. Rowlock after cleaning. This is first primed with Hypalon single part adhesive because the fitting is made of rubber.
A/. PVC Adhesive does not stick to Rubber
B/. PVC Adhesive will stick to Hypalon Adhesive

Zodiac Transom
7. Removing old adhesive from base of transom.

8.  Single part Hypalon adhesive and cut down brush ready for priming cleaned up wood so that the PVC adhesive will stick to it.

  1. I have a Zodiac Futura Mark 2 which I purchased new in 1996 we use it for a couple of weeks each summer to tow our kids around and grand kids now… however this summer when I pulled it up and after sitting in my driveway for a couple of days I noticed the transom has come unglued on both sides and literately was unattached… It’s in excellent shape, with the exception of the transom, it looks exactly the same as when it was purchased… So HELP PLEASE.. your instructions were very clear however I do not know of what materials my Zodiac is made. In the original brochure (which I still have) they talk of ‘Thermobonding” and “Strongan” fabric do your instructions still apply to my Zodiac as well as the quantities suggested …. Thanks in advance for any assistance.

  2. Hello Martin, Removing the old adhesive can be a chore, but using Polymarine 2093 Solvent (or MEK as a next best substitute) will work and a heat gun to gently warm and soften should help do the trick. (Do not Sandpaper PVC) You can prime with the 2 Part Hypalon Adhesive (it’s not essential to mix in the curative for this).

  3. Hi, I am about to attempt a transom repair on a Bombard AX2 foldable inflatable. The wooden transom would seem to be loose in the rubber mounts and it is difficult to see if any adhesive has ever been used. Does this seem right? Also the transom mounts I assume are rubber and have become detached from the tubes. In order to re-attach should I prime the rubber mounts with Hypalon adhesive and the use 2 part PVC adhesive to attache the tubes? Is it OK to prime with 2 part Hypalon?(no 1 part available in store).
    Fianally having great difficulty removing old ashesive. I sispect some previous attempts to reapir have used various glues. I have used Acetone as well as Meths to try and clean but not the best effect. Any ideas?

  4. Hi Tim, The best solution for Rubber to Wood, is simply to use a 2 part Hypalon (rubber) Adhesive as the normal application instructions. Hypalon Adhesive readily sticks to wood.

  5. I have an AAKRON BM380 whose transom needs refitting. Thank you for the detailed instructions by the way, i just have one question. The transom mounts i believe are made of rubber. These appear to be still well affixed to the PVC tubes and i do not think i need to touch them. This leaves me the main task of reaffixing the transom (wood) to the rubber mounts. In your instructions, it appears that single part Hypalon adhesive affixes to both wood and rubber, but not PVC. Since i only need to affix the transom to its mount, can i use single part Hypalon adhesive for the whole job (no PVC), or is it better to still to prime with the single part Hypalon adhesive, and use the PVC 2 part adhesive? If i still should use a PVC 2 part adhesive, how long should i leave the single part Hypalon primer for before applying the PVC bond?

  6. Hello Phil

    Thanks for your question

    Please check out the adhesive guides below which gives detailed instruction.

    The humidity and temperature might be an issues in a UK November.

    The correct primer/solvent for the tubes (see instructions) would be an advantage.

    Also are you sure your Zodiac is PVC some around 1982 could be Hypalon.



  7. I have attempted a transom refit on my 1982 Zodiac Cadet.
    I cleaned off all the old glue with Methyl Ethyl Ketone (MEK) then wiped entire area with acetone. All old glue removed.

    Then I used 2 part hypalon adhesive to prime the rubber parts then 2 part pvc adhesive to prime the tubes. When both parts had been drying for 30 mins I then put a second coat of 2 part hypalon adhesive onto rubber & another coat of 2 part pvc onto tubes. I then left for 5 mins to get tacky & bonded together.
    48 hours later I have removed the ratchet strap and peeled the transom off as it didn’t bond.

    Where have I gone wrong in the process?

  8. Thanks for the super quick reply. I really appreciate it. Thanks again!

  9. Hi Gerry, yes you can use ‘Flexithane’ a flexible paint for Rubber & Hypalon to seal sticky rubber components.

  10. The rubber oarlocks and rubber that attaches the transom to the inflatable are sticky. Can the be cleaned up so I can reinstall them back to the dingy?

  11. I had a question about priming the transom with Hypalon adhesive. Do you apply one (1) or two (2) coats and how long do you allow the coat(s) to dry before applying the PVC adhesive? Thanks!

  12. Hello Ryan,
    Yes a 1 x 70ml Polymarine Hypalon Adhesive tube and 1 x 250ml Polymarine 2 part PVC adhesive pack will be enough to attach your Transom.
    Your tip for replicating the transom is very good – great idea!
    Thanks for your kind comment, were pleased to be able to help.

  13. Hello, I just want to know how much product do you think I need to buy for redoing the transom. It is a Zodiac just like the one in the illustration and it’s PVC. I know I’m going to need one part Hypalon Adhesive for the wood transom and 2 part PVC glue for the rest. Thank you for the great tutorial. I have one quick tip to share. I have to replace the whole transom, so I bought a sheet of 3/4″ marine plywood and used the old one as a template. I then rough cut it with a jig saw then I used a 2hp router with a pattern router bit. You just place the old transom over the top of the plywood and it trimmed it perfectly, exact match.

  14. Hello Clive, If your side fittings are rubber, then rubber to wood with 2 part Hypalon adhesive is good. However, you would then need to prime your rubber fitting with Hypalon adhesive before fixing it to the PVC tubes with PVC adhesive. Please check your fittings they could well be PVC too (like our Zodiac example).

  15. I am about to attempt a transom repair on a pvc Typhoon. The transom side fittings look like rubber, similar to your zodiac, so do I still use pvc adhesive with a hypalon primer for the wood?

  16. Hi Marco, The tubes are best inflated to re attached to the transom. Clean up and re attach the bottom too if you think there is a chance it may be affected in the same way as the tubes/transom.

  17. Hello, on my tender the tubes are poorly glued to transom and needed to be taken apart, do you suggest to take away bottom too for best final results, even if it seems quite ok ? do you need to work on inflated tubes when fixing the tubes to the transom ? Thank you 🙂

  18. Hi Richard, Good question. Yes the single part Hypalon Adhesive is used as a primer because it will stick to wood. PVC adhesive does not stick to wood, but it does stick to Hypalon Adhesive. The instructions on this page have been edited slightly to clarify that old adhesive is cleaned off and new adhesive is used as a primer (single part Hypalon) prior to final gluing with 2 part PVC adhesive.

  19. I need a clarification on the priming step. On the transom bare wood, are you using polymarine one part adhesive on the bare wood then letting it dry? Is this used as a base for the final gluing of the fabric to the transom using 2-part polymarine adhesive? My confusion is that all instructions require the all adhesive be removed before applying the 2-part adhesive. Thanks

  20. Hello Steve, Weigh up the advantage of leaving the transom fittings in place (if they are sound) with stripping down, cleaning up and re-attaching. Try a dry run at replacing your transom (without glue obviously) to pre check for any difficulty. Under inflated tubes to start with before higher inflation with straps. All the best, Polymarine.

  21. I’m just about to have a go at doing my boat. The transom side fittings are still attached to the boat. Would it be easier to take them off and glue them to the transom first, or leave them on the tubes? I had a hard time getting the transom out of the fittings and wonder if it will be very difficult getting it back in.
    What do you think?

  22. Excellant step by step photos gave me confidance to attempt job – thereby saving costs of finding and geting someone else to do the job.
