I have a 4 blade 18 pitch prop. But my boat full throttle only goes 30 mph at 2400 rpms.... What prop would be best all around for my boat.. its only 16 ft. long... i check the motor and it stated that the max rpm at w.o.t should be between 4200 and 4600 what is gonna give me the best performance. 130 hp. 4 cyl. bowrider.
