REFLECTOR: Mt prop govener IO-540 300hp

[Andrew Ellzey]

I have the prop govenor that came with my engine, has anyone ever adjusted their own or asked a repair shop to remove the data plate and adjust your govenor to what you need to match a new prop?  Has anyone on the reflector gone through this situation already and know of a good repair shop to use. Information on the web about prop govenors seems to be scarce. As does information on what pressures are required for props. I know that there are others that have purchased used engines on the reflector, and someone should know a model number for a woodward govenor that would work.

Andy,

As far as I know - yes - attached is a Lycoming IO-540 comparative... on page 7 of the .pdf, "Narrow deck" engines have a propeller governor drive ratio of 0.895:1 and "wide deck" engines have a 0.947:1 ratio.

I have a narrow deck IO-540E1A5 (Narrow deck). So you are saying that my govenor gear drive ratio is .895:1?

Per Eric Greindl @ MT-propeller Entwicklung  GmbH

P-860-20 with .947:1 governor gear reduction ratio  (wide deck)

P-860-3 with .895:1 governor gear reduction ratio  (narrow deck)

My IO-540K1G5 is a wide deck engine - so I have a P-860-20.

John

P.S.
They also sell/sold a P-420-17 (narrow deck) and P-420-5 (wide deck) - the P-860 series is manufactured  by MT.

The Velocity web site is down so I would like to ask what the model number of the prop govenor is that Velocity suggests to use with MT prop for a 300 hp IO-540 engine. I would also like to ask what model number other builders are using?
