I'm sitting on that fence at the moment too. While I believe the pcu5000 to be the better unit, I'm not sure the cost difference justifies the expense.

I believe the question being asked is "Is only getting 2550 RPM maximum acceptable when a (I)O-540 narrow deck governor is installed on a (I)O-540 wide deck engine".
I wouldn't think so.
Especially when Van's Aircraft could provide the correct governor. I am aware of them knowing about this for at least three years.
Just my opinion.

I have talked to American Propeller about this and they claim the PCU is much better governor. The cost savings will be a repair or overhaul time. They claim the MT will be shot and almost not rebuild able, vs the PCu will be a very easy overhaul.
I am thing of using a PCU and Whirlwind 3 Blade prop combo. I talked to the Engineer who designed the 3 blade Whirlwind prop and very much like the design and thing it will outperform the MT. I am not a fan of wod/glassed props that MT makes.
Just my 2 cents worth.

How long is the service life of a prop gov and what type of maintenance is involved?

I received the same feedback on the governor from my engine builder.
The prop was still in development and “in testing” when I made the choice, if I recall the only prop more expensive at the time was the aerocomposite, and the Carbon Lycoming. In the end it was the standard 2 blade for me. half the price to boot!

If others are reading this and they have an older Rev B or C prop governor, MT will update it to latest version without charge if you have issues.

Phil,
My MT gov P-860-3 specs sheet says 6 yrs or 2000 hrs whichever comes first. No idea if it will make it or not. Only time will tell.

I have a wide deck IO-540-N1A5. After Kelly posted the gear ratio reminder I was worried about my governor I received from Vans. I have the -3 model for narrow deck so I called MT. The tech advised me that it will probably work as is. If it doesn't reach full RPM there are options. First try to adjust the set screw that is safety wired by rotating it out. If that still doesn't work I call him back and he talks me through internally adjusting the governor. Either way I won't have to send it back to MT. This is also because I have the latest mod on the governor.
