Appreciate all the responses. I'm like 600-800' ft elevation so not really an issue there. I opted for the OJ945 simply because it was the factory upgrade option and also about $75 cheaper than the next one that appears to be basically the same. I also got the quick change kit/etc and may swap it out at some point this summer but will sleep better knowing I've got a backup prop should anything happen. Can't wait to get some time behind the boat come spring. I did find out that it's 3000lbs factory ballast with the Maxsurf package I ordered, and I have an old 750lb fly high with a tsunami pump to play around with if needed, but hoping it's great out of the box.
