I have a 2000 Yamaha 150 that stalls at idle after being run for a while. Just had both fuel pumps replaced by a Yamaha dealer and had fresh plugs installed. Motor seems to run good until after it is up to operating tempeture. Then either stalls when idleing or when put into gear. It also runs fine above idle speed. I've done a compressino check and tried to check all fuel lines when seem to be good. Any ideas would be appreciated.

Re: 2000 Yamaha 150 Idle Problems

I was just having the same problem with my bro inlaws boat 2004yamaha150 and found one of the plug wires was getting a bad connection new wires and no more stalling but the idle bounces around between 600 and 900 rpms not sure if this is normal but it seems to be running pretty good.
