While I don't have IPS drives I do have Zeus, which BTW Grand Banks has now dropped. The only problem I've had I'd the auto pilot is crap and there is no replacement. We have also lost 200 -250 rpm at top end but still maintain our original speed at other than WOT. I decided to try new technology but if I had a chance to do it again I would use shafts that I used for 40 years. The maintenance is also about $1k more per engine. Very maneuverable but as BandB states thrusters on either end would do the same thing.

It probably is the wave of the future and I'm sure will get better. The only problems I e had are the auto pilot and loss of top end rpm and speed (which I might correct by turning up the HP via computer on the Cummins).
