Outboard Problem

[flounder_smacker]

i do a little outboard work on the side and this guy had a 50 with the same exact problem. he ran 3 cans of seafoam which usually gets carbs right and nothing improved. so i tore them down and soaked them in carb dip which will eat skin off the hand for 2 hours and no good. i tore down and soaked the carbs 4 times which usually only takes one time to clean it good. after that i called the yamaha rep and a week later he came and picked his brain on it and after a week of him cleaning them in sonic bath with the best carb cleaner yamaha could buy still dirty. he called yamaha and they sent a new carb and after that it ran like a top. on that motor it was the bottom one which is usually the one to act up. ive seen yamaha replace blown power heads on out of warranty motors. they stand behind their product. talked to a rep once and said they goodwill about 4 million worth of parts a year. just sweet talk them a little bit and i bet they will shuck out a carb.
