Screw hole repairs in transom
Submitted by Jadeo on Sun, 2018-10-28 22:10
Hi fellas, looking a bit of info and guidance as to what is the best way to repair screw holes in the transom of my boat? Also does anyone know where I could get a thick piece of plastic or something that I can sikaflex over the top so I don't need to put any more holes in my boat for transducer adjustments? Cheers in advance

I have just filled a heap in
I have just filled a heap in the back of my boat. Drilled it out slightly with the next size bit, then drilled around 5-9mm into the face with a 10mm bit then filled up the hole into the hull with sikaflex then topped it off with bog. Sand and re-apply flow coat.
I am doing a major job on my boat so there may be better ways but that's what I am doing

Hence filling the 10mm hole
Hence filling the 10mm hole with bog prior to flow coat.

To flood weld the hole, sand
To flood weld the hole, sand and paint would be best.

What you can do is drill, tap and fit a grub screw with sealer. If your transom is at least 5mm it shouldn’t be problem to tap thread into it.

Epoxy
Drill out the hole with a countersink bit , fill with epoxy thickened with micro balloons. Let dry sand back , skim coat with more epoxy if needed . Prime and sand then add two coats of topcoat colour. Swompa do yourself a favour and drill out the sika and start again !!! . It will bite you in the bum sooner or later

Cutting boards
Jadeo, am pretty sure I have seen those thick white plastic kitchen cutting boards on trailer boats used for transducer mounts.
I couldn't comment on their suitability but am sure others could.

Cheers lads
Went to my local Chandleryshop in the Mandurah mariner and got a product called Epifill. Got a good size off cut of thick plastic from Cut Out Plastics. Got home and took out the screws from the previous owner and f$&@ me a little bit of water came of the bottom ones. Thankfully it would not have been anymore than than about 30mls. Glad I decided to it bit the bullet and do it properly. Some people just have no bloody clue at all.
