Hello everyone,<br /> Once again I find myself with a question for the experts here. In febuarary this year I bought a 1975 Fabuglass with a 70hp Evinrude on it. After haveing the carbs rebuilt,water pump and the plugs replaced its been running like a champ. Havent had a single problem so far. But today when I went out to take the batteries out for a charge. I noticed a small puddle of blackish oil under the prop. After further investigation its apparent that there is a oilish build up inside the prop area. <br /> I had left the motor down in the run position after running her with the muffs lastnight. I dont usually leave the motor in this position so this is the first time I have noticed this oil puddle/ build up. <br /> I at first, thought that maybe it was a leak from some seal behind the prop. But after loosining the foot plugs I see the oil inside the foot is clear as can be. <br /> I run this motor (or try too atleast) at a 50:1 ratio. <br /> I was just wondering if this build up is simply from my running the motor to rich in oil or should I be worried and rush the boat down to my tech? <br /> I was mixing the oil by eye with a empty oil quart bottle. But recently bought a measureing container. So now the mixture should be right. I have noticed since useing the measureing container that the motor isnt smokeing anymore. <br /> And one more issue someone out there may be able to resolve for me.<br /> Since buying the boat I have been running her strickly in the lakes around my area. But I am a hopeless saltwater fisherman who drives 200 miles for a single day at the peir in charleston S.C. And I was wondering if there was any truth in what some people say about there being a diferance in the motors designed for salt and fresh water. <br /> And infact if there is a diferance would a motor as old as the one on my boat be subject to such diferances?<br /> Thanks in advance for the help <br /> Patrick
now im a happy salt water fisherman!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
