I'm running a 21" High Five right now on my 2008 Crownline 180BR with a 4.3 TKS. The best description I can give on that prop is that it's just "OK". I'll give you a brief rundown of what I've tried so far. I bought the boat in 2011, and it came with the original Black Max, which vibrated like crazy, but was still good for around 52 mph GPS at 4800 rpm's. I wasn't a fan of the vibration, so I swapped to a 4 blade Alpha 4 20" aluminum prop, and I run around 48 mph GPS with the same exact rpm's, but extremely smooth operation. I also like to wakeboard and play, and I weigh 225 lbs., so I needed some low end grunt. I chose a PowerTech OFS 17" 3 blade prop which got me about 38 mph, but was horrible at maintaining speed with my weight behind the boat. The PowerTech would launch out of the water, but blew out in turns and was hard to maintain plane at low speeds So, here I am now with the High Five. The High Five does a little better than the Alpha 4 at getting on plane, but not so much for a nearly $600 prop. Now, if tubing is your thing, the High Five operates like the boat is on rails. But wakeboarding and skiing, it is disappointing to say the least. I cannot make it blow out in turns, but I lost 8 mph GPS top end, and fuel economy went to garbage. Best I can get is 40 mph GPS, and that's "cruising" at 4000 rpm. With the Alpha 4, I cruise at 3500 rpm around 40 mph. As with all boats, the hull determines the speed, and the shape of the wake. The prop you get shouldn't hurt the wake at all. Now, trim tabs will affect that, but your prop choice shouldn't. I have actually heard good and bad things about the Vensura, and the Rev 4 on deep V boats, and since I would say my overall best performance comes from a 4 blade aluminum, I'm hoping to duplicate that with some SS 4 blades. Good luck with your choice. Hope this helps you out.
