I had a 27' baja with 350's and alphas like cuda. The tie bar was a great add. I never changed mine from both rh rotation, but i always heard it wasnt as much for speed as for handling. You probably notice a lot of prop steer when you go from 50 and back of the throttles. It probably has a nice pull to the right. It would help with that, but in the long run, probably not worth it.

Two right hand turning props will make the boat heel to the left most of the time. Wait until you pop one of the alphas and you can get a left hander for the port side.

Docking is easier with counter-rotaters turning out. I don't think you'll go faster enough to notice it.

If you decide to make the switch, and it's an alpha drive, all you have to do is get a counter rotating lower. They make the Alpha a counter rotater by moving the drive gear from it's normal position in the rear of the case to the front, behind the propshaft carrier. That is the only difference. This also depends on what Alpha drives you have. (R, MR, GenII etc, etc.)

It actually ran faster with the old right turning ballistic props in the one motor in reverse mode, both props turning right!

Needless to say, I kept the counterrotating props on and move both throttle handles in the same direction. <gg>
You can't run an alpha in reverse. They are designed to handle power in forward only.
