Spinning a lab bed set of 4 blade 28s from throttle up. Boat is maxed at about 80-81. Rev limiter alarms singing...gauges are reading about 5200. What can I try to get the r's down and speed up? Btw...these are river props and are a little chewed up...nothing major

were at in pittsburgh do you boat? if you are maxing out labbed 28's that are nicked up i would think to try stock or labbed 30's. your nicked up props are prop mafing them slip a lil more than normal so if you get them fixed you would be faster but still on the rev limiter. also might want to look at hydromotive props, they are right in ohio.
