New Honda 225 with nema 2000 capability. Using Garmin gs10 gauge. Temp goes up to 220 degrees on gauge when cruising. But no warnings or buzzers from honda control components. So I took a temp gun out on a cruise and shot spots both on the water jacket and heads while cruising. All temps were acceptable and in range except for the reading at the very top of the water jackets (which is also where the water temp sensors are installed). Sure enough, those high reading match my garmin gauge. But that is the only place on entire engine where I receive a high reading. Could there be an air lock? And how would I clear it? Or is it something else? I have also noticed that my water pressure (as shown on Garmin gs10 gauge) reaches about 12-14 psi when cruising (4200rpm). Can't find the spec on water pressure range anywhere. Please help. Dan
