Is this correct for this model??

Hello, I just got a 1975 165 hp mercruiser that has had work done on the outdrive and was noticing that the exhaust bellows is not connected to the out drive itself. I was just wanting to know if this is how it should be. Thanks

That will be ok,it just gets louder when you trim up.

No, that's not how it should be. It should be a bellows, not a tube. The tube was used on big block V8s to relieve exhaust back pressure. The 6s and 4s were never fitted with tubes. It's probably been done by a previous owner who was too lazy to do the job right The bellows are harder to fit, but I prefer them... You can leave it like that, no harm will happen, or you can (as I would) replace it with the right part...

Yes, That's fine, it's a Mercruiser "exhaust tube". It's cheaper, and easier to install, and gives you a little louder exhaust sound.
