I've been running the 2083 for a couple years now. I like it. Pulls a little bit stronger than a 911, though it's not a huge difference. You lose a few (more) mph on the top end for that low end grunt though. I don't care because I will run at 3-4k RPMs across the lake regardless of the actual speed I happen to be going. With the 2083 you get most of your speed at 4k. As you keep accelerating up to 6k, which I would never run at, you hear a lot more noise but don't get much more mph. If you happen to already have a 911 and it's not too bad, I wouldn't recommend dropping the cash unless getting a 'little better' low end pull is burning a hole in your brain. With the 2083 it's best if you don't run at WOT because the RPMs can get pretty high. Since we are at 6000' and pretty much only wakeboard (sometimes wakesurf) it works well for us. We sometimes go down to 4300' and when I first got the 2083 I would swap the prop back to the 911 at that lake, but after a couple times I stopped doing that. Overall I'd say it's too little pitch at 4300' but only because you can run the RPMs too high if you don't pay attention. It pulls and holds speed like a tractor though, and that's all I care about. My 911 got into an altercation with a rock so while it needed work I had the prop shop reduce the pitch a little and increase the cup a little. It now pulls very similarly to the 2083, so that's an option too.
Here's an anecdote for you though - after running 911s and 2083s for 3 years I'm a little tempted to send my v drive to Walter during the off season to switch out the gears from a 1:1 to a 1.5:1 so I can get a 4 blade prop with a higher pitch to get more pull and possibly better fuel consumption. However, I'm only considering this because I have a v-drive oil leak so maybe it's worth the upgrade while it needs other work anyway. I haven't done it yet so that tells you that the 2083 and the modified 911 is suiting my needs just fine. (I'm also not looking forward to the process of figuring out the correct new prop to use as I'm not aware of anyone with a V215 with a 1.5:1 vdrive...)
