Re: 83 volvo 125aq rt or lft prop

The rh or lh prop rotation are for dual outboard installations. One engine drive clockwise the other counter clockwise. It's there to help prevent torque steer from having both engines pull the same direction. If your's is rh as you say, you can't change it without changing the lower gear case to a special lh orientation. If your prop is currently a LH designation then it was originally made to be installed as one of a pair of engines. I don't know why you would want to change it from RH to LH as you state in your posting. LH props are hard to come by so stick with the normal rh prop.
