Replacement tach systems

[Jim Rainer]

Anyone who has replacd the Cessna tach system in a 337G or any model with an STC'd replacement or one done with Form 337 paperwork, please let me know what system you used and how much paperwork was involved.

There are a number of manufaturers out there but none I could find with an STC'd system for the 337. Some are "FAA Approved" but my mechanic is leary of exactly what this means.

I am at the point where I think installing a brand new system is preferrable to chasing the old wiring and re-working the mags and possibly ending up with a new or used Cessna tach doesn't make sense when there are brand new systems out there.

Thanks
