will a 14x8 master airscrew prop too small for a 25cc homelite? or its just in the range? i have a 15x13 2 blade apc and a 15x12 4blade apc and the motor doesnt sound right, like it cant really handle the prop size and pitch. will this 14x8 be able to make this motor run more effecient? this will be for an airboat
thanks!
