Help with Evinrude 40hp 2 stroke

[Finnz922]

Over the last year our older Evinrude 40hp 2 stroke has developed a most annoying issue. It works fine when hooked up to a hose or in a large trash can filled with hose water, but when we get in in a lake it idles terrible and cuts out when under 5mph and in idle. Seems like it struggles to get fuel but like I said it works fine at home at all speeds and in idle. Have any of you experienced anything like this? We have taken it in to a guy almost a half dozen times and he says the motor is in great shape and works fine which is comforting until we get to lake and it's deja vu all over again.

Have you checked your fuel hose. I had a horrible time with something like this and it was from my fuel hose being eaten away from ethanol. I was lucky that I did not blow my motor.
