I wrote yesterday about rpms and got some help i have 2 diff props 1 is a 2 stage pitch and the other is just a big pitch 1st 1 is a k-19 and the other just says 19 on it. The k-19 wraps out around 6200 and gets me 48-50 mph and the other 1 wraps out at 5000 and gets 42-44 with the 1st prop it sounds smooth just a little high strung and the other well just the other. The boat is 18'6" a bass tracker my motor is a 140 hp mercury 1979 vert 6, 3 carbs i mix 50-1 using blue marble oil lots of people say that that motor should run 60+ anyone help, cause i fish tournaments and need to get there quick.
