FAQ:

Q: Is a boat GPS speedometer necessary?

A: Whenever you’re out on the water, accurate speed readings are critical. In terms of both safety and situational awareness, a proper working boat GPS speedometer is necessary for adhering to posted speed limits as well as planning trip schedules or itineraries.

Q: Why is there water in my speedometer tubes?

A: As noted, there should not be water up in the tubes. The speedo (or MMDC black box if your boat has one) should work on air pressure. The air pressure in the tube keeps the water from coming up. So, if water is getting up, that means there’s some sort of leak up under the dash that is letting water push the air out that end.

Q: How to tell if my Speedo tube is bad?

A: Best advice I’d give is get rid of those pitot tubes and go with a through hull paddle wheel or GPS speedo. Much more accurate and reliable. There should not be water in the tubing past the balance tube. If you’re getting water all the way up to your speedo in the dash then the tube may be bad or clogged.

Q: Why is my Speedo filling up with water?

A: If you’re getting water all the way up to your speedo in the dash then the tube may be bad or clogged. Best advice I’d give is get rid of those pitot tubes and go with a through hull paddle wheel or GPS speedo. Much more accurate and reliable. There should not be water in the tubing past the balance tube.
