Just got this motor today and was planning on replacing the impeller before i used it as I dont have a history on the motor. While looking for the impeller in the iboats store i didnt see 1 listed, only 3hp evinrude they list is up to 1978. Is this motor water cooled or air cooled? If it does need a impeller any tips on this perticular motor? Any other things I should go over before i put it in use?
