prop issues ??
I have a 2000 32 active thunder with 500 hps with a refresh to about 560 per side, my original prop is a 30 b1 labbed heavly, verry thin, i am now getting into the rev limiter at 5500 it runs 86 on gps up 3 mph from last year,so i tried a stock 30b1 only spun it 5300 at 83 mph but made the boat porpoise bad on top end, then i tried stock 32 b1s with a cupp in them im told to about a 33 only spun them 4700 at 83 mph but again porpoise bad on top end but did pick up 5 mph at 4000 rpm, my original props do not make the boat porpoise at all. im lost what to try next.
