Westach replacement CHT & EGT probes

[Leo Langston]

My old Westach 6 position EGT and CHT gauges and probes were installed years ago in my Navion under a TSO. Several probes have failed or no longer give a reading. I must have at least 1 CHT for my engine per the TCS. Westach no longer makes TSO gauges or probes. Can I legally use the Westach non TSO probes to replace my failed ones or am I forced to replace the whole gauge and probes with another system? I don’t have the budget to install a $12k MV-50P or other fancy engine monitor this year.

Search eBay and salvage yards or do a 337 with the non TSO probes

337 for non TSO probes is probably the easiest solution. Not sure I want salvaged EGT or CHT probes.

Agreed, I just looked and there are a few used CHT probes on Ebay. They want $60 for a used probe..
