Cobalt Condurre 300 Thru-Hull exhaust dry-rot.



It seems to extend down about 6-8"...hollow sound.

Everywhere else is solid.

Glassdave will hopefully chime in...lol...

My thought was to clean out the soft dead wood between the transom inner and outer glass.
​
Use a good penetrating sealer on the then exposed good hard wood. (In the now hollow core area)

Then refill the hollow with a glass fibre resin system.

Something along those lines.

I'm not averse to pulling the inside glass off in that section, but it seems this maybe a solution that does not compromise strength.

Arneson ASD6 twins.

No engine weight on transom.

Thanks,
