Filling holes on Transom

[Chris]

The nobber who rigged the Honda on Pigs Ear fitted the top bolts too close to the top of the transom (about an inch from the top!)

So going to drill new holes two holes down on the bracket and move the bolts down 2 holes (1.5")

I would like to fill the old holes and wondered what the best way is to do so. Wooden dowls (slightly oversize) and some epoxy then knock them in with a mallet till they are slightly below the surface to allow some gelcoat filler to be used to finish off the surface seems the best solution to me.

Any better solutions?

Thats what I did when I filled the holes from the botched fitting of my A frame by the manufacturer.
I just used dowel, epoxy and gelcoat filler just as you say and it seems fine nearly a year later.

Assuming its a wood core transom...

You'll probably find that your need to sand/grind out a "dish" into the gelcoat and partly into the glass. If you just put a disk of gelcoat on the end of the wood bung, the differential expansion and contraction of the wood and glass will make a nice circular crack in the gelcoat. So bevel out the edge a little.

Yep, I would fit 2 new ones so you would have 6 bolts in total

Had thought of that and agree its probably the easy option..

I was just being a bit pedantic and not wanting a transom full of bolts.

My 'Leccy Pal Lee had this dilema with his Stingray chavboat. The solution was, a laser cut stainless plate which was boxed over the top of the transom and came down the inboard side enough to cover the first row of holes and came lower on the outboard side. It was cut, shaped and fab'd by a commercial kitchen outfit. I can get a pic, it looks dead smart.
The redundant holes were filled with GRP bridger.

I made mine like this to protect the transom from new and one from the old searider in powder coated ally

Ditto.


Just a wee curveball from the stainless plate dept:

I removed one of them from my transom when I changed the engine. Looked wonderful & shiny form the outside, but tround the back was a bucketload of salt and oodles of corrosion. It was so bad my plan of using a corner of it to mount my Nav lights was promptly abandoned!

Thing is unless it is perfectly seald (a utopuian fantasy in itself) water will get in, eventually evaporate and leave the salt behind. the rest you can work out!

[biffer]

I'd have a think about it first. Whatever you put in the transom won't be as strong as original and then you're going to drill another hole quite close to it. I'll be inclined to leave it as it is

If the boat isn't going to be left in the water all season and a careful Sikaflex job is done, all will be good in my opinion. I disagree that the briney can't be kept out.

Bummer..As a dead man walking from a previous hole drilling thread :-0 I suppose a thread about the relative percentages of engine falling off with 6 ilo 4 bolts would go the same way too

Yes with a smooth bottom too, not the Penrim non slip finish

Plate hard against transom = V. thin layer of Sika. Even if you coat the whole thing there is going to be relative differential expansion & contraction. Even Sika has a life expectancy when cured and will eventually go hard = hairline crack on next expansion / contraction = ingress...... And that before you induce vibration form the engine.


Once agian this may turn out to be one of these "agree to disagree" marmite subjects, but based on what I found, I'm steering clear!
