Replace speedometers?

I have a 1989 2001, which has Airguides. They are full of bugs, the lenses are cracked, and only one works semi reliably. They are accurate when they work, which is maybe 70% of the time.

What options are there for replacing them? Still love this boat and want to keep up with repair/rehab.

I see this guy which looks OK in all black. Probably wouldn’t need 2 of them. Not sure what I would do with the other speedo spot.

I put these in my '89 2001:

Faria Euro Black GPS Speedometer

Very very happy with them. Not original, I know, but period correct to me, and, they look the part in the boat:



They work flawlessly. And with little effort, the dash can be brought back to original (as with all my other customizations), since my original Airguides are nicely kept in bubble wrap in a safe place and my wife has been warned not to touch them

I looked for a second hand working Airguide (one of mine leaks water due to the bellow in it. Fixed it and it held for five years, but now broken again), but the prices for them are way up there
Also, the nice conversion from Nautic Laugic comes at 375$ for the pair: Airguide GPS conversion
With the Faria's from Defender.com I have two speedometers with internal GPS for 160 bucks…

PS: for the more observant among us, the 1 MPH difference is gone now. This pic was taken on my first test run with them. They show the same speed now.
