Quick question. I suspect the ethanol their putting in the gas today is slowing eating the lines on my 89 Johnson 20 HP Outboard. I have cleaned the carb 3 times "third time I put an inline fuel filter in" But silly me never did think of taking the lines completely out of the motor and blowing them out etc. But I noticed the two times I cleaned the carb there was a very fine, what seemed like the color black sediment in the run off in the container I was using when flushing it out, which leads me to believe that maybe the lines need to be replaced, and if so how might I obtain them? there are 3 or 4 lines I believe going from memory, do I need to replace all of them or mainly just the larger line running off the fuel pump? Or is there a kit that is approved for ethanol that I may purchase some place? " I tried looking on here and on google but I can't find such a thing"
The idle jet was getting dirty before and it would cough/sneeze at certain RPM's trolling/slow cruising. That is fixed and it idles fine now, but now it the powerhead has a slight shake to it at WOT, which I dont know now if my high speed jet is dirty or maybe the fuel filter is to big? :S It is one of those universal in line filters that are see through made by SeaSense.
But my gutt tells me it is the original lines on the motor and the ethanol is slowing eating them? Can anyone confirm this might be the case? and if so possibly let me know which lines I need to replace?
