Hey folks, got a question...I dropped my boat off at a guy's house to have my GPS speedo installed (Faria Chesepeake Black SS GPS 60 mph Speedometer - this one: http://www.boatersland.com/faria-chesapeake-black-ss-60-mph-gps-speedometer.html). He texted me today with this: "I tried to install speedo and it will not match up with the tube setting from the other one. It's a different gauge." Does this make any sense? I thought it would just be a matter of putting it in the dash and hooking up the power source? It kinda sounds like he's trying to hook up the tube from the pitot...? Thanks for any advice!
