[EP11] Fibreglass Boat Transom Replacement From The Outside

Published 2021-05-23
Nearing the time of sale of my beloved Haines I discovered the transom had water ingress and rot especially around the engine bolt holes and rear well drain holes due to a poor design. I replace the transom from the rear using marine plywood and variety of methods and tricks I researched and thought up myself.

This series features the semi restoration of a very cheap Haines Signature 530F in need of a lot of work. It aims to educate people on how to perform good quality, but very budget orientated repairs and modifications to all things mechanical especially boat building.

  • As someone who does this for a living (at least 3 transoms per month anyways), you did a GREAT job. There is a few things I would have done differently, but, you did a great job on this. I think this is one of the best videos I have seen on a DIY transom replacement on YouTube. Biggest thing I would have done is not to ever put any plywood on the boat again, but since you did, you probably would have been better off pre saturating each piece with resin (especially on the end grains) and glassed it with that 1708 Biax before putting it to the boat. I think this transom will DEFF hold up and you did great!

    I did my transom in 2005 and this brought back many memories. I separated the deck and went from the inside but so many of the techniques we both used were the same. I too was obsessed with no cavities and made it super strong and millimetre perfect. People at the time said it was "over-engineered" but 16 years later it's still solid as a rock and in rough weather I like knowing my boat is stronger than it came out of the factory. Outstanding video and thank you for sharing your project with us. Iain

    Yes, a speeded up video, without awful β€˜music’ blasting out, that I have to mute and then miss dialogue. Thankyou πŸŽ‰πŸ‘πŸ‘πŸ‘.

    I know I am a Yank. lol But I have to say very impressive. I have done many many transom repairs. Your is a job above. Thanks
  • Nice work, I liked the narrative and step by step description. You'd make a good teacher. Keep up the good work. Thank you.
  • Great video, I have the same boat and your video will help as I have not tackled fiberglass before. Great tips through out video, thank you. Nice to know the transom has not got a full double plywood sheet construction.

    Better than the last person I watched try this

    Great job, hoping the boat I have on my channel doesn't end up needing a transom! Keep up the great work.

    I used West system Epoxy for all gluing and filling. Stronger, more fresible and seals water. Nice clean job!
  • @gregredden3871
    Great video. Really appreciated. I have same boat with a transom I think is in the same condition. Thinking of repowering so thinking of replacing transom first.
  • Awesome great work on boat, you are a master of repairs thanks for the video I enjoyed it

    Well done! I put a new transom and stringers/deck in my boat a couple of years back. I did it all from the inside but used many of the same techniques. I used epoxy instead of polyester resin. The epoxy is more expensive but as I understand it, it will adheres better and has a longer pot life. If I ever do it again, I think I will go with polyester resin since I have some experience now and I can go quicker.
  • I have two old boats I need to fix transom on! This will be very helpful thanks man :)
  • Nice Job! Didn't know one can rebuild transom from the outside, now I do! Thanks!πŸ‘πŸš€
