There are a few boat models originally fitted with A-4's and standpipe exhausts although most were iron rather than stainless. The ones that come to mind are the Tartan 30, Tartan 34C, Ericson 29 and Newport 30. There may be others but we run across those frequently. Of those I mentioned I'd say the Newport 30 is the least likely.

here is a Tartan 34 stand pipe

Well I have this stainless steel exhaust if you can use it let me know I am in Vancouver BC Canada. Like to see someone Make use of it.
Case of beer and it’s yours! Beer can even be optional.... Just put it to use!

Cheers

my old Ericson 27 had a standpipe exhaust located in the port lazaret. not sure if that's the one or not.

That looks as though it's a port-side mounting arrangement. My Ericson 32 is a starboard-side standpipe - but it has a vee-drive, so the engine is mounted 180 degrees away from the way most engines are situated.
