How to test a speedometer

I have my boat all winterized and have a new plate for my speedo. How would I check to see if it works?

Are you just want to see if the needle moves? You can blow in the hose with your mouth. They work on air pressure. (actually the difference between the static water pressure and the moving water pressure in the pitot tube with air in the tubing transmitting the pressure to the gauge). Otherwise, the hose just needs to be clear between the pitot and the speedo.

Just blow lightly. It doesn't take much to get it moving. Any compressed air will be too much. Even from a spray can of air.

Check the hose from the pitot... and move your way to the speedo.

I think if one of my speedo's crapped out and no longer worked, I would get the GPS replacement module and forget about the pitot tube.
If you put a hose directly to the back of your gauge and it didn't work, then there must be something inside the gauge that is blocked or corroded.
