My 1998 Evinrude 150 Intruder has all of a sudden started stalling when I shift into forward or reverse. It doesn't do it all the time. It always cranks right up and idles perfect. In neutral I can rev it as high as I please, but as soon as I shift into gear it goes dead. From there it'll crank right up again, but do the same thing when I try to shift again. I can play with it back and forth and eventually get it to pick up, and it'll run great then. It's pretty random as to when it does it. It seems to be after I've run for a while and then stop and sit for an hour or more. It doesn't do it when I first crank it up for the day (after sitting all night/several nights); and it doesn't do it if you run it, kill it, and crank it right back up. I've tried pumping the bulb when it does it and that doesn't help. I called a repair shop and they said a new type of fuel was being sold to the US now and that it was designed for fuel injected motors and that it would cuase a carburated motor to do this during hot weather. He said there is nothing I can do about it and that it would do it from now on - at least in hot weather. I don't know that I believe this because most everything else I own (ATV, lawnmower, weedeater,......) has a carburator and they aren't stalling under load.
