Hey all,<br /><br />I have the boat in my sig...<br /><br />There is a speedometer already on the boat, but I'm not real sure if it works... If i understand how the speedometer works, it just requires a pick up mounted on the outside transom that picks up the water as you go, and the speedometer goes off water pressure!?!?<br /><br />What's a good speedometer for under 50MPH?<br /><br />--------<br /><br />The Tachometer, obviously would have to connect into the engine, so I wanted to know if all engines are capable of having tachometers, or if the engine has to have certain wireing/components?<br /><br />If I am able to have a tachometer, can anyone give me some more insight on what all i would need to do in order to connect one?<br /><br />Thanks for the help,<br /><br />-TheChad
