Steve,
I am contemplating the same thing as my own emergency procedure has pulling the prop as one of the steps and my practice has shown a far better glide ration. I would want to retain that option.

Also, I am wondering what is in the MT prop that they require it based on calendar since the hours for TBO is 2000? Also, what are the typical symptoms of a MT governor going bad? This is beside these cases that are certainly structural faulty.

Well, today I got a price quote on overhauling an MT 860-4 governor at American Propeller in Redding. It is $1000.

Anyone recommend an overhaul vendor for less than that? I imagine that the shop in Florida will be overwhelmed with backlog addressing the SB. So, where else?

Yeah, Redding quoted me the same to redo my MT P860-4.

Stockton Propeller, Stockton California quoted $850.00 http://www.stocktonpropeller.com/

MT (Florida) quoted $800.00. No confidence.

I decided to buy a new PCU5000X for $1200.00 from Aero. Comes with a warranty. I installed it and its very smooth. Works great. The PCU5000X requires a 72 month rebuild.

The Hartzell PG S-1-10 seems like a great choice considering no rebuild required until 2400 hours.

Glad I went with a Hartzell dependable and last longer than an engine and best of all American made.

I'm considering replacing my MT governor with a PCU 5000.

I'm interested in the practical experience of PCU 5000 owners regarding the PCU's ability to govern the engine to slow rpm when the prop control is pulled back (during simulated engine out, or at idle, for example).

Can any PCU 5000 owners comment on PCU governing operation below 1700 rpm?

(APS tells me the PCU 5000 will govern with oil pressure as low as 40 psi, but I didn't get a sense of what rpms are in the governor's controllable region.)
