Good looking glass work. I bet you are glad to have that done.

Looks pretty clean to me. You might consider a little cpes on the keyhole insides.
Any holes in the repaired transom should be overbored; filled with thickened epoxy and then rebored as needed.
Leaky Holes are what end up killing these.

Is cpes useful even though I used coosa? How much should I overbore the holes?

I thought I saw wood in the keyholes.
Only overbores for wood.

Oh, shoot. That looks like the garage on closer inspection. Sorry. For some reason, I thought you had jist added some coosa and the wood was still there.
No need for cpes! Hope I didn't screw you up. Very sorry if so.
Cpes won't hurt to have on hand if you ordered some. It is a great product for stopping any rot on questionable wood.

Hi,
I came across this discussion as I am currently working on my Bertram 25 flybridge.
I took the motors out and I'm swapping them for another set of 165 Mercruisers that are fresh water cooled.
I cleanup the bilge but the mounting holes for the front engine mounts are rotten out. I drilled a few holes and wood is bad and soft.
I will be cutting out the front engine mount area just as in your pictures and replace it with Coosa just as you did.
My question is, how did you mount the new engine mounts? Did you drill lag screws into the cossa after ? Or did you bolt through with some backing at the bottom.

It would be best to start a new thread. All rot must be removed or the new mounts will rot out as well. Start a new thread in the repair forum and we'll help you there.
