I know ,merc love to keep warranty claims to a minimum , all manufacturers do it and I would do the same just wanted to give you some real live experience .

The xr s on my hustler whit diesels turning 34 bravo s make the same bang when put in gear at 600 rpm as my xr on the 21 at 900-1000

i guess shut off key just as u shift so drive is still spinning a little to ease up on shift yoke.

Glad to know I'm not the only one fighting this shift issue with the XR's. I snapped the shifter linkage a couple seasons ago going into gear, luckily it lock into fwd so I made it home. Like Bor I'm spinning a big pitch [35p or 37p] so it's loaded heavy, which makes finding neutral super tricky when the fluid is cold. Compounding this problem, there is no way to ignition cut out the diesels..

What I've done to compensate on the Dmax is "Torque Limit" the engine at idle speeds. Have your Hustler or Cumnins rep check for that option in the ECM tuning. It's Bosch fueled, so I'm betting it's an option. Lowering my idle rpm to 600 helped me some, but limiting the engine torque to 40ft lbs at 600-800rpm range has made mine shift 50 times better than the stock config. Still tinkering with it, but I've got it working great for the most part and should add more life to the drive.

Well the mod worked great, and like some suggested, when I go to shut down the engine, I just push her in gear as the engine is just shutting down, easy peasy, and then I start it in gear. I just take my time pulling up to the dock, and my engine fires up everytime. I think this will make my XR live longer, how much longer with 620HP pushing it, time will tell.
