I have a set of 32 Bravo's that have been worked a bit getting them closer to 33's. They have added cup and although not labbed I had nearly an inch of the leading edges sharpened somewhat trying to get some more rpm (this left a portion of the blade at stock thickness for strength).....they still didn't work for my application so they are just sitting in the garage. For comparison, they run about 150-200 less rpm's than my labbed 32's. I'll let them go for $650.00

What effect did the work have on the RPM? Were they better after the work was done?

Rpm's really didn't change......added cup reduced rpm a little, sharpening them got that little bit back. The labbed (thinned) 32's I have do get a little more rpm but they are completely diffferent props.....I ended up with some Maximus that were the better all around prop so the Bravos haven't been on the boat much.

It sound to me like your motor is happier at the lower rpm...what makes you think you want rpm's higher...did you dyno? If there is more power at 5600rpm you should go faster...not slower. Your slip is very low...the 36's especially !
