I have a 30' Enforcer w/twin johnson 300gp's (4.0's). The starboard side rotates clockwise and port counter clockwise. I was told that this is more stable, but if I would swap them i.e. starboard counter clockwise and port clockwise it would lift the back of the boat more giving a little less stable but more top end. Is this correct? I have more than enough bow lift as it is right now. Any help would be great thanks.

Not sure how much more top end you may get from switching, but ive always run props on my V's outward, the way you have now. I wouldnt sacrifice a stability for a couple MPH's.

You'll find each type boat will run differently with each direction. Rotating out "usually" means better ride and handling in and around the docks. Rotation in on "some" boat hulls can mean a tad bit more top end but lack in the other areas. You just have to give it shot and find out for yourself how your boat runs. Swap your props around and throttle in reverse to test. If you like it, swap the cables around. If not, swap the props back done deal....Good luck.
