That`s not what I wanna hear.

Have we reached a 100 fountains on OSO yet that have reported non sealed exhaust tips that rotted the transom.....seems to be a few a month anyway.

Also Seems so odd that so many years and models and same damn exhaust tip deal.

No dog in this hunt but it seems so obvious and so inexpensive. Why didn't Fountain seal the exhaust tips? Helll, with labor and material you couldn't be talking about $50!

It would be better to build the boat with an exposed solid wood transom and stringers. That worked for hundreds VB of years until some knucklehead decided to encapsulate the wood in fiberglass.

That sucks!
I've seen more issues with later models it seems. That said, a transom job isn't as big of a deal if you don't mind doing some work yourself. If the glass work is outsourced, shouldn't call st more then 5000.

Most surveyors are a joke. Get a rubber mallet and tap every inch of the transom inside and out. You will hear the rot.

And what's the difference in sound ?

Ahhhhhhhhhhh,winter is here.

If there is a difference, there is a reason. It will sound hallow or more like a thud if it's just really wet. Transoms begin to rot at a through hull. So if it sounds different near the top of the gimble or around the pipes vs. in the high corners, you probably have an issue. Next step is to stand on the tabs and drives to see if there is any play. Last step is low ball offers

Same difference in when knocking on drywall with your knuckle to find a stud. One is a hollow thump, and the other is a solid knock.
Best bet is to get a moisture meter though when checking out a boat.
Just like with a Rinda scanner; you can go in with a group of local boating friends and share such expensive tools that don't get used overly often.
