Anyone know what the make and model number of this prop governor? Fuel pump is in the way sorry best pic I have. (it's leaking oil) It says Garwin on it and numbers stamped on the side 5320. I searched the logs and there's nothing in there for the prop governor ever being worked on or replaced. It's in a Mooney 1968 M20C Lycoming engine O-360-A1D with a 3 blade Harzell prop. I would like to replace it with a PCU 5000 hopefully a drop in replacement. I would rather replace it with a new one since I have the mags, vacuum pump, battery box, lower cowling and hoses out of the way.
