the wheels are 750 and no 8v71's in diesel form aren't but once converted to petrol form then yes they are
What because the Diesel engines they are designed for spin the opposite way?
depends if it was off a twin engine boat, they were counter rotating engines, depending if a port or starboard motor
On the boat subject, unless I'm out of touch with large installations, but certainly sports boats and the like, one engine is run with the gearbox in forward gear and the prop cut standard, and the other box runs in reverse with the prop cut reverse.
only one would be counter-rotating .. starboard i think
no prop walk ..
sorry the port (left) engine
