Jimmy, You are better off to spin the motors in different directions, that way you are putting all the pressure on the lower gear, when you turn the input CW and right and prop. And the other one CCW with left hand prop. The rotation is based on facing the input or front of the drive..
Friend and I were just discussing CCW rotation on a blower motor.. and the possibilities..

Hope this helps!

Counter engine will not work on a Bravo, the thread on the upper shaft creates the force to engage the clutch. Spin it opposite and it will not engage.
