I have a 2003 Yamaha 50 hp 2 stroke. I bought it new. Until recently it has worked perfectly barring a few minor issues, water pumps, etc., never any fuel related or mechanical issues.
Recently it has begun to die out on acceleration past 1100 rpm. When I get to 1100 rpm and attempt to go faster it bogs down and dies. If I the choke lever to "emergency" it will run but not very well. If I then immediately switch to "Run" position it will run great. When I stop it is back to dying out.
I have replaced all the fuel lines, spark plugs, and oil lines in addition to cleaning the carbs as best I can without removing them. It is firing on all cylinders and will run on any one of the cylinders by itself.
My next move is to take it to the shop.
I'm not inclined to do that just yet.
Any suggestions?
Alan
