I've got a new to me Mercury 125 two stroke for a project I have. That being said I'm trying to find out where the speedo hookup is. I know I can mount one on the transom like a pontoon uses but I'm under the impression that these motors had one. There's a fitting on the top of the lower unit in the front that looks like a rubber hose could to attach to, might this be where it would connect?

I have that connection on my 40 hp motor but it constantly clogs up. Switched back to the pitot tube and many fewer clogging issues.

Chances are that's the pilot tube fitting. You can blow a little air in the pilot hole, if it comes out there, you got it.
