Reviews
I purchased the unit from Spruce in 2013 with zero issues on my float plane. Surviving winters -50 there has been zero issues.
Installed this unit onto my Cessna 150 with a Lycoming O-320 conversion. No issues with oil pressure or temperature readings. Very happy with the unit.
3 aircraft on our field have the OPT-1 oil pressure/oil temp dual gauge. All 3 have had oil pressure sensor problems . Mine had 750 lbs oil pressure? Would NOT recommend this to anyone. Just over a year old and zero help from electronics international. If you buy this don’t get rid of the original gauge just put a tee in for the oil pressure sensor.
