EDM 900

Obviously neither of those shops know how to do the install. Call Don Maxwell and get an estimate from him, just for fun.

Have you considered the idea of installing it yourself? It's a lot of work, but it'll save you about $5,000.

Doesn't that require you having an A&P as well as knowing what you're doing, neither of which I possess

You just need an A&P that is willing to supervise and sign off your work. Many of us have gone that route, but if you're not comfortable with such work then you should keep shopping for a good shop or mechanic to do the work.

My EDM930 install was installed a while ago by a local shop (not the avionics shop) and I agreed before the install on a flat rate based on 38 hours for the install. There was a lot of panel work involved because all the old gauges had to be removed. For this purpose he had to redo parts of the right panel.

I do not want to fly without an engine monitor any more. It showed me already several engine problems early, like an induction leak on one Cylinder or a fuelpump which was starting to break down.

The photo shows the panel after the 38 hour EDM930 install:

 

The above photo is now history and the cockpit got a complete panel update and looks like the following photos:

I installed my GEM back in 1992 with the IA signing it off. He was there to consult on things like how/where to run things and how to secure them properly.

Guitarman is an airline pilot and he did his own 900 installation and had his mechanic sign off on it. The installation is not that complicated.

Agreed...installation is tedious, not complicated. Aside from potential panel fabrication/modification (if needed), the bulk of the effort is routing wires from panel thru firewall and to the proper locations around the engine, and of course securing them. You'll need to run a power wire from the battery and add a circuit breaker. The fuel tank senders get wires, and an OAT probe needs to be installed and connected to another pair of wires. Mooneys don't have great access behind the panel, so the task is frustrating at times, but doesn't require any advanced skills.

But if you're not comfortable changing oil, then I wouldn't attempt it.

I've changed the oil on it, but this sounds like a completely different animal, I'm just worried about getting in over my head and then having to pay a bunch of money to have it finished anyway

KS is right about it being tedious.  Lots of running wires.  You will have to make a few fuel hoses and mount the transducers. However....

Everything is marked VERY well and the instructions are clear.  I found JPI to be responsive to my questions during the install. 

I have an excellent A&P that is willing to teach me his tradecraft and that is invaluable.  I had to learn to make fuel hoses.  I love learning new stuff!  To be honest, without him I would have gotten stuck in a couple places.  

Probably spent about 40 hours on the install.  i would think an experienced shop could do it quite a bit faster.
