Thanks for the response! Speedo's don't work but I have new speedo tubes that I need to install so this is very possible!

Next place I'd look is the exhaust hose to transom connection, then I'd look for a hole in the muffler(s).

Next place I'd consider is the platform brackets that are mounted with lag bolts into the transom. Water pushing the platform when slowing can open up a loose lag bolt....

The neighbor also has a valid point but that is usually at slower speeds...

I have a strong feeling that it's the rear platform brackets. The entire platform seems pretty loose, especially when weight is put on it.

Now the only time i get a bunch of water in the back is when I do back turns....lol
Rubrail and everything will most likely be redone this winter so if I don't find it by then we'll see!

Definitely possible, water does get pretty high when coming off!
