Yes, many marine engines especially older marine diesels (and gas) had one engine standard (ccw as viewed from the flywheel) and one clockwise, or reverse, rotation. The marine reduction/reverse gears used could not handle full torque output in reverse, or had a different ratio in reverse, and twin screw boats use counter rotating propellers. Otherwise the torque of two props turning the same direction will cause the boat to list over to the side as it runs. However in the 21 years I have been working on marine diesels 99.9% of them are both standard rotation (in a twin application) and one transmission is run in "reverse" and one "forward" but you"d not know from the control levers at the helm as the levers go "forward", the switch is made on the bottom end. I know Detroit used their own Allison marine gears and they (I think) could not be run one forward and one reverse, hence the one left hand and one right hand engine. Gasoline inboards that used Borg Warner "velvet drive" marine gears could not take full power in reverse or something like that- I have no real experience with those gears- but I have done tuneups on many american V8 marinized gas engines and when you ordered a distributor cap it was marked with the cylinder numbers for standard and reverse rotation. I know the large 3500 series Cats can be ordered in reverse rotation. I hope my gibbersih has not confused too many people.:)
