My boat has 10 analog dial gauges at the lower helm and another 5 up top. They are old but quality Telcor gauges. Each "system" (oil pressure, oil temp, trans pressure, water temp etc) has a modular with resistor pot allowing you to calibrate the gauge.
My question is what is the best way to get an accurate measurement to adjust the gauges.
For the pressure (oil, trans and fuel)I think just installing a mechanical gauge will be find. Its the temps I'm not sure about. Do you think using one of those laser temp gun thingies is accurate? I took it out this weekend and set the engine at a constant rpm for two hours, then took readings around the engine block with the laser.
The oil pan was a steady 185 oil temp gauge read 195. The thermostat housing was 180 the water temp gauge was 190.
Would you adjust the gauges to match the laser?
