My thought would be to get it through break-in and get around 10-15 hours on it. Then see what it does with what will be your lightest load you'd ever run. At that point, you can start dialing it in via prop pitch and engine height. If you don't have a jackplate, a good starting point is to get the prop shaft approximately 3.5" below the bottom of the boat. With your lightest load, you'll want that engine to spin as close to 6200 rpms as you can get. I wouldn't worry much about the PVS plugs, those are only for hole-shot performance and add a little air over the blades to get them to spin up easier from a start. Once up and on plane, the water pushing past the holes seal them off and it does nothing for your top end performance. It's about the last thing to play with prop wise.
The Bravo is a decent prop overall and pretty popular in the walleye boat arena when it comes to the bigger 20 and 21 ft boats. The others that are popular are the Tempest and Rev 4. All things being equal I always found my tempest to be the fastest. They have a lot of bow lift, are naturally more efficient being a 3 blade, and are aggressively cupped. It'll be the worst of the three for hole-shot, planing speed, and bow control however. A Rev 4 will turn hardest. It's basically a 4 blade version of the tempest. It's a big wheel with aggressive cupping and rake. They are normally a little slower on the top end because they turn so hard but will handle better and be a little quicker accelerating out of the hole. I had a DAH Modified Rev 4 which was my main prop, it was the best handling prop of no less than 10 different props that I had tried on my last boat. It did give up nearly 5 mph on the top end to a DAH modified Tempest Plus. The Tempest was really just my smooth water tourny prop but it was smokin fast. On that boat, I found the Bravo to be a touch slower than the tempest, but with significantly better handling and holeshot. It wasn't as good as the Rev 4 but was it also didn't suffer the speed loss nearly as significant as the Rev 4. Time will tell, the new boat was outfitted with a 21P bravo which I was impressed with in stock form last fall outside of being a little under-pitched as I was running up against the 6,500 rpm rev limiter of the Verado. I tried a "new" to me prop guy over the winter, Croxton Performance Propellers, and hopefully he's got it dialed in, I'll know in the next few weeks when I get to this seasons maiden voyage. Certainly looking forward to it!
