Brett labbed,cupped and raked a set of Bravo 1 26 pitch 4 blades for me and I gained 4mph. My boat is a 93 Cafe running bravo's and 560 hp per side. The boat was running 74-75 in chop last year. I took the boat out yesterdaywith 2/3 tank of fuel and 2 guys in flat water the boat ran 78.9 on gps! This by far the best money I have ever spent on the boat. I know a couple of guys that will be calling Brett next week.
