We just got our 43' Donzi ZR in with them and the NXT drives, WOW!
What a nice set up. The only down fall I can see is you having to run the 92 or better octane fuel in them. They sound awesome, idle at 750 in neutral and 700 in gear. The transmissions are a little bit on the stiff side to shift but so are some older Bravo's. We had the boat at the Annapolis boat show this past week, it brought a lot of attention.
