So as i have said in several different posts I am ground up restoring my boat. Part of which is new dash/ guages. Most of the guages on the boat were inopperative anyway so I want to get new gauges and whatever else is needed. What will I need sending units? I want mph, tach, amp, fuel, and tilt. So my question is whats a good place to get these guages off the internet and also what all will I need to install everything new? thanks josh
