Hi All, <br />I have recently purchased a boat with a 70-73's 50hp mariner. I have used it twice now and it starts everytime has never let me down and produces a good stream of water. I put it in a bin filled with water to run fresh water after use, i have recently noticed the water becoming very oily and coating the bin with quite thick oil... Is this normal... When priming the fuel it pumps right out of the carbs air flaps... again is this normal... <br /><br />If anyone can advise or help i would be most gratefull. <br /><br />Regards<br /><br />Paul
