Come on you guys, TRS is yesterday's news. Any more than 525 HP and you're on borrowed time. Put on a pair of 4 blade Bravo 1 props and you'll wear out the TRS gears in short order.
That smooth shift comes with too high a price. A very heavy hydraulic transmission that steals 25 HP from the prop AND pushes the two heaviest things in the boat forward 18 inches! Even a Top Gun with TRS is a MF to work on. Where do you stand? Ever change a bilge pump or float switch?
The Bravo drive has much better hydro dynamics and is lighter in weight. If you have one that shifts too hard, you probably need a shift cable adjustment. If you MUST have a sissy shift, then install the Power Shifters available.
Of course the early Bravos were worse than they are now. Testing them for five years in Lake X was a waste of time. Test those puppies out in the ocean where they belong. I can make an Alpha live forever in Lake X!!
