O.K., I have a 24' tunnel with the 377 6.2 mpi 320 hp, bravo 1.50 and a Revolution 23p 4-blade prop. The boat weighs about 3600 lbs. My problem is my top speed is about 52 mph @ 4000 rpm. Is the prop wrong? I would like to be at least 4800 at WOT and at least into the 60 mph area. What should I do??
Thanks, Joey
