I'm redoing the gauge panel on my Sea Ox with a 92 Evinrude 225. It currently has a tach, trim gauge, hour meter and fuel. All of the current gauges are junk. I want a tach and fuel gauge, but what other gauges would be recommended? Volt/Ammeter? What else? I'm going to relocate the hour meter to a spot in the back as it doesn't need to be monitored constantly. Suggestions are appreciated!
