My setup is as follows. The engines are fairly near the centerline of the ship so the distance to the prop is about 15' from aft of the transmission to the prop. At the transmission I have a CV joint connected to a non-marine industrial shaft that is 4' in length. At the other end of the shaft is the matching CV joint which connects to the thrust bearing. The Thrust bearing is a python drive but I think the aquadrive is similar. >From there my stainless prop shaft runs parallel to the waterline out to the prop. This prop shaft is supported mid way as well.
