Prop to pad 2 3/4". 25 tempest plus. Have had boat 4 years and can not get better than 62.8 mph. Rpm will run 6000 and still have more. Water pressure is 32 psi. Boat really doesn't have much bow lift but a hell of a hole shot. Have moved jackplate all the way to 3 1/2 pop. No real big difference. TryinG to get input as to what prop I should go to without buying different ones. Jackplate is 14" , was on boat when I purchased it. Can't get max rpm the way it is. Afraid or will over rev if I stay in it. Any help?
