The speedo on my 2001 22ZX - (350 Magnum & Bravo Drive) stopped working today while underway. The guage is stuck on 42MPH. Does anyone have any suggestions on how to trouble shoot this ? Help would be greatly appreciated....

Pull the line off the back of the speedo and see if it drops back to zero. If it does the line is plugged. If it doesn't then the speedo is broken.

If the line is plugged you can try compressed air to blow it out but be careful, most of the time the hose isn't clamped on so you could blow it off a fitting on the outdrive and that can be a royal pain in the ass to find and reconnect.

Check the hole on the front of the drive. Most likely plugged.

This happened to me a lot untill I went to a gps speedo.Use a drill bit to probe the hole on the bravo.Then take the speedo air hose off the back and blow air thru it.

If you use a drill bit... make sure the drill bit isn't attached to a drill! ;-)

I heard doing this would be the easiest way to make the boat go faster
