Do you have the present prop size and the rpm and speed?
Difficult to select an all around prop.It is like selecting one gear in a standard transmission car that will do best for all purposes.
It will be a comprimise based on your activities. and your present performance.One of the pros may be able to select a prop based on hull design,weight and the reccomended WOT rpm of the motor.
