My Lehman 120's have EGT pyrometers in the exhaust elbows (ports are cast into the elbows), and analog gauges at the lower helm (not the upper).
I don't understand why one would need these on a non turbo engine, particularly one where the relationship between throttle, RPM and load is pretty much fixed (can't lug the engine towing up a long hill, etc.). Indeed, my gauges seem to correlate just to speed and nothing else. I struggle to come up with an engine failure/wear issue that I would pick up on these gauges before another more obvious sign somewhere else.
Anyone care to defend their inclusion as I re-do my helm? I'm always inclined to keep an instrument if it's already there, but only if there's some point to it.
