Are you positive that it is a counter rotation motor? Reason I ask is because the literature doesnt specifically say but the nomenclature is the same for our inboard center consoles.

you didnt say if your wheel was left or right handed??
general guide if you have a normal rotation motor is
1-1 gear- right handed wheel
1.5-1 left handed wheel
2-1 right handed wheel-
