Ok here is the story I bought a Baja 320 that was missing the right side out drive. The guy lost most of the parts except the lower propeller shaft and gears/bearings. I bought another outdrive. but its the wrong rotation. I assume I can change the shafts/gears in the lower unit and get the correct rotation that I Need. My question is the bearing at the end of the shaft closer to the nose cone/front of the lower unit are different size am I able to change bearing race's or are the lower unit housing different I would assume the housing are not different from a mfg stand point would cost to much. Just want input to make sure im correct.. thanks for your help.

TRS housings are machined for left and right hand rotation just different bearings for L & R hand

+1
Different front and rear bearings (due to load)

Thanks thats what I thought. gonna swap lower unit shaft/gears soon.
