set up custom port for default ssh connection in tramp

I am wondering what is the best way to set up a default port that is not the standard 22 port. I regularly log in with tramp to remote systems and would like to avoid having to put in #1234 every time I connect.

My tramp config (org-mode) looks as follows

* Tramp
For TRAMP to work with ssh-key, install the programm ssh-askpass
 (https://github.com/markcarver/mac-ssh-askpass)
 C-x C-f /ssh:you@remotehost|sudo:remotehost:/path/to/file
