Having a weird fuel issue with my 1989 115hp Evinrude 2 cycle. When initially pumping the ball, I have to pump and pump and pump for a really long time and it never gets hard but I get enough through that I can start the motor and then I have no problems. I tried replacing the ball but got the same result. I have only had the boat for a couple months and it has only recently started doing this. There is some kind of in line filter that is about as big as an oil filter on a car. Could it be that this is clogged and needs replaced? Any info is much appreciated.
