I took the boat out today and there was a steady stream of water that was coming from the dash. I took the dash off thinking I would see the speedo tube was disconnected. They were both connected. The speedo on the left had some water in it. Any ideas? 89 prostar 190. Thanks. 1st post btw.

Probably a busted diaphragm in the gauge. I had the same problem, and it's relatively common. Unfortunately, the diaphragm cannot be bought, and you'll need a new gauge. Luckily there is a company that sells them new (http://www.airguide.com.au/index.php?p=1_1) and you can buy them used from anyone who has added Perfect Pass.
