I have a 2004 35 Open with 8.1L's The starboard trans has whined since day 1. There is occasionally some chatter at idle with the rudders turned. All goes away in reverse or at higher idle. ZF service said the whine is normal on the starboard because of the counter rotating. I have over 2000 hours on the starboard trans-nearly all idling/fishing hours. Love the engines and the boat!
