I am just starting on the FWF part of my RV-9A build. I will be using an RV-200 prop and the Jihostroj P-920-028 Governor (the engine is an IO-340). It's time to drill the holes in the firewall and Drawing 19 has a note for one hole on the upper left part of the firewall that says, "Prop control cable (Aft mounted governor) drill 5/8 dia. Hole".

Before I drill the hole I'd like to verify that the Jihostroj governor is aft mounted and that the hole location shown will work.

Thanks!

It's not the governor that defines the location, it's the engine. It will either mount on the back of the engine, on an adapter on the accessory case, or on the left (pilot's side) front of the engine case. If the governor is aft-mounted, then the hole location shown on the plans will work.

Here's a semi-lousy photo of my Jihostroj governor mounted on the back of my O-360, for reference. Just visible to the right of the battery box.
