Greetings all, I went outside today after our first real Idaho freeze and found oil on the outside of the motor near the keel. I inspected my main motor, 28hp Evinrude, and my kicker, 6hp Evinride and found both motors to have oil leaking from a small hole above the prop. Is this acceptable or did I do some damage. Last time the boat was out, I did not run it outside the water to clear out any lake water. Anyone have any tips if its not too late on protecting my motors while I use them in the freezing weather ( Trout and Ducks ). Thanks in advance!
