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.

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.

Hartzell

Harzell toyed with the idea of selling pusher propellers for the Velocity, and provided a test unit to the factory. However, the testing was not successful, I believe the pressure pulses from the wings were too high, but I'm not sure.
