Yes the piece in your hand has a clip that connects with the nipple on the drive.
You should be able to order from a Merc dealer.

Re: Speedo not working

Local Merc Dealer ordered a replacement for me, comes as two plastic parts, one to connect to the speedo tubing, and one that connects to the drive. Mine was around $10 to fit an Alpha I, gen 2 unit. You might want to use a zip tie around the tubing after you push tubing onto the fitting. I don't recall for sure but think there may be different versions of this part (way the two pieces hook together) depending on year of drive/serial #. May not matter as long as component parts of your replacement fit together and work. Dealer could easily check.

I broke mine by forgetting to disconnect it before splitting off the lower drive to replace an impeller.

Re: Speedo not working

Since my last post on this, I looked through my shop manual on this.

OEM shop manual #14 April 2001 edition for Alpha One Gen II shows two versions of this speedometer connector, one for 1997-1/2 and earlier and one for 1998 and later. The earlier version uses a twist and turn and pull operation for separation, the later version uses a push in on a release button followed by a pull to separate.

My drive is an Alpha One Gen II, original since 1991, and my speedometer connector is the earlier version. The invoice for my part lists a part number of 22815956A1 and it was called a "Coupling Kit."

I don't know if there is any other difference in the two versions such as internal orifice difference, size on threaded end/thread pitch that goes into drive etc. I would doubt any difference in the versions other than coupling mechanism but don't know for sure.

If a Merc Dealer is near enough, you could bring in the part together with the serial # of your drive and get a quick match.

They are completely different. The original poster has the early version.
