According to alcor, these are the correct probes for my M20TN acclaim with TSIO550-G1. They work and install as OEM, but the clamp has to be trimmed to size and deburred. TCM M-0 required that they be safety wired, see AC43-13 for best practice.

Q: On the Alcor Basic EGT gauge 46150, how many degrees do the major and minor tick marks represent?

The large ticks are at 100 degree each starting as 1200F and the small ticks are 25 degrees each.

Q: Is this simple system compatible with a certified engine on a Cessna 150K model? And, how does the exhaust probe mount? Thanks!

This unit uses a 3 1/4 - 3 1/8 hose clamp. Please check with your local Aviation office to see if this PMA is ok for your aircraft.
