I have an 89 ski nautique and both speedos died. The right one started to leak water under the panel. I assume that the problem is it’s the gauge and not the tube. Are these gauges available or does Airguide do rebuilds? Or is there any tricks to getting these working. Thanks!

It could be something easy like the hose leaking where it pushes on to the barb on the back of the speedometer, or it could be the bellows is leaking at the solder joint.
I'd take both speedometers out of the dash and pressurize them with air and see if they respond. (or see where they might be leaking) 30 psi gives about a 50 mph reading, so if you use some pressure less than that, like 20 to 25 or so, you won't over range or damage the speedometer A compressor with a regulator that you can adjust will work good) There are other things to look at, but this should be a good start and give you some information. PS.....Airguide went the way of the dinosaur  If you end up needing one or two try a post in the parts wanted section. Somebody will probably come along and tell you to get them fitted with GPS internals

Just like to add to Kens ideas is that sometimes the bellows split from water getting in and freezing.Sometimes they can be silver soldered back together. Like he says you'll know more when you get inside.
