HI, about new to prop.question is,same boat same motor what is the rpm that a mercury lab finish bravo1 24 will turn over a bravo 1 24 regular.thank

rssteiny

200 to 250 more rpms

Actually we designed the standard template to turn 300 more rpm. However, every boat can be a little different. We have seen 200-400 R's.

im new to trying out new props. dumb question. what are labbed blades and what do they do? i got a 23ft wellcraft nova spyder with a owens built 496, bravo 1 and a 23pitch no cupping, turning way too many rpms, 6,000. i changed it to a 21p with heavy cupping and its doing way better turning about 5500 rpms at 66 mph on gps, this local prop shop is trying to sell me a 4 blade 23pitch with heavy cupping but not sure what to do at this point. do you have any prop that might help?
