The M-500 is selected by many operators for new boat construction, re-powers and upgrading of propellers. The excellent design and increased blade area provides superior and higher performance without increasing propeller diameter, which may be impossible due to clearance or tip speed consideration. The M-500 is the top choice on installations where heavy vee-struts, dead wood or other hull appendages are agitating the water flow to the propeller. In addition, the M-500 is the choice where vibration caused by resonance is a problem. The blade design reduces vibration caused by the propeller, achieving smoother and quiet cruising.
