Just bought a boat with a pair of 2005 Yam F225 4 strokes. They start instantly and run like string trimmers on meth.
HOWEVER, the port engine just shuts down on its own after prolonged idle. It will stumble a second or two and then just die. If cranked, it will not start. If the primer bulb is vigorously pumped till stiff, the engine starts just fine and all is well, unless you need or want to run at no wake speeds for a while. It will just quit again.
So, I have been running down the creek with the port engine above 1500 rpm and the starboard at the idle detent. It seems as though that amount of power will keep it running.
Sounds to me like there is an air leak between the tank and the engine which is of no consequence when running the engine at high power, but manifests itself under low power settings.
My plan is to start at the tank and tighten every fitting I can find in an attempt to fix this.
Any other suggestions?
Many thanks.
