"My F225 will start perfectly and idle perfectly for a few minutes then stall. I squeeze the primer ball a couple of times then it will do the same thing. I repeat the process of stalling and starting maybe 3 or 4 times and the motor will run fine as long as i don't shut it off. Then the chain of events will begin again. By the way, there is a brand new high pressure pump and this problem only happens under 1600 rpm. Any suggestions."

Mount your primer bulb in a vertical position with the arrow pointed up. Had the same problem and it fixed it. Yamaha recommends mounting it this way
