    I have an old hand held automobile GPS that has a battery. It has a feature called "dashboard" that shows mph. That is the best way. No pitot tube to attach to the transom and no tubing to route/step on inside the boat. I still do like the old speedometers for the looks and they do give a comparison with different motors, trim etc. If you do get an old type one, be sure to get an appropriate range for your boat and motor. (for example if your boat goes 15 mph, a speedometer with 80 mph range will hardly move the needle.)
