Transom repair

[freespirit3]

Whilst on a lovely holiday last year in Scotland managed to do a trip to Mull from Oban and then did the last 15 min trip to Staffa, well worth while, stopped for some photographs and whilst there a freak wave hit the back of the boat and snapped off the elephants trunk. Managed to repair next day with expanding foam and a tapered wedge shaped by my brother in law

Trunk style was old style with a tube bolted to the transom, cleaned it all off today, have a new one to fit flush to the transom.

Question is what do I use to repair a few cracks I can see in the little tunnel through the transom leading to the trunk.

Would like it to be white and obviously water proof, but as its inside the trunk probably won't be seen

Any thoughts, fibreglass, polymarine epoxy of gel coat repair, Trying to add picture from iPad but it won't let me, will keep trying.

Thanks for any ideas

Before, with the face plate removed and adhesive on the transom

Now ready to refit with new trunk, just need to tidy up the hole through the transom.

Thanks for looking

Could you sikaflex some drain pipe in the hole if you can match the size

We fibreglassed a piece of fibreglass exhaust tube (from asap supplies)into the hole and allowed it to pass through the hole far enough to clip the elephants trunk to on the outside which saves the need for the plastic plate and seals the transom all in one go
It's a bit of work but permanent once it's done

Good idea.

Is that portion of the transom solid fibreglass or is there timber there? If it's solid glass I wouldn't bother with much, maybe silka the pipe in or a light coating of epoxy resin around the hole. If it has timber there then I would look at fitting a bit of pipe with epoxy around it maybe, the fibreglass pipe will be less brittle I imagine.

I have just done similar myself and used domestic pipe. I wanted to ensure longevity so wrapped the pipe in epoxy and bi axial fabric for strength

It looks exactly like the drains on the raider I had it had originally been flow coated but over the years it had cracked where the ply laminations were that's why we decided to do a permanent job to prevent water ingress to the ply
I had to slightly enlarge the hole with a hole saw which revealed good dry timber then inserted the grp exhaust section with some thickened resin and allowed it to set then I ground a radius on the inside and wrapped csm onto the transom and into the tube then finished off the whole thing with flowcoat it looked spot on when it was finished and I'd say pretty permanent

You can just see the repair in this picture before final flowcoating
The grp exhaust was about a tenner for 200 mm long which was just enough for 2 trunks

Thanks for all of your comments

Really appreciate it, going for the beef it up idea. Many thanks
