Guys,
So, after the rebuild last winter, and the cam swap and other changes made this year, and final tune worked out, the engine is running strong. Over this last winter, I picked up a labbed Bravo30 after reaching out to Brett about the labbing. I had really high hopes. The leading edge had been thinned nicely, so I figured I’d really swing it. While I can turn it with ease, I’m not getting anything out of it. I’m still running about what I was before the engine failure that lead to the rebuild; not quite, actually. Prior to, we were running a consistent 76-77GPS, and I could swear I saw 78 once or twice on those perfect conditions days. Now, with a stronger engine and “more prop”….

I’m not positive, but I’m pretty sure a fair bit of the cup has been removed from the trailing edges, and it’s killing the grip. I know it really likes to try and blow out during the later stages of planing, and I have to really baby the throttle to get it to lay down after without continuing to blow out. Once we’re underway, it’s good. Cruise is still about the same. I know I can swing more prop, as I’m still at 4000RPM @ just a stitch above half throttle, 4500 with damned little more throttle, and 5K before 3/4 throttle.
I really need to try a stock 30. Any suggestion of other options? 5B? Hydromotive?
Thanks. Brad.
