I have a LH rotation bravo 1 that I want to upgrade to imco but it spins the opposite direction can I change the rotation to LH?

Ya put it in reverse . Bravo drives run either way . Change cable at the control box

Yup - You just change the cable to the other side of the shifter so that it pulls or pushes opposite of what it is doing now.

Just did this on my twins.. very easy and once I realized that the cables run straight up to the levers, I switched mine in about 20 minutes. 4 screws for levers and needle nose to get cotter pin out of rod holding all cables in place.
