Light twins not using contra-rotating propellers

It's the same prop. Just put it on backwards.

The cost of manufacturing two versions of the engine and
recertification of the design is not worth the small
advantage. Most light twins were designed and certified
over 40 years ago.


What would be all the unique parts?

Camshaft has to be different.
Crankshaft probably is drilled differently for the oil passages.
Starter.
Oil pump.
Magnetos.
Vacuum pump, I assume?
Prop, obviously.

That should be about it?

No, it is different as are internal engine parts and the
accessories.
