Any help or advice given is greatly appreciated by me. Thank you in advance. My Yamaha Outboard 175 hp motor recently started to sputter and then die when I am in idle. I suspect that the problem may have to do with the fact that the boat has been out of commission for a few weeks and wasn't used due to a broken steering cable. (That's another story). Does anyone know what the cause and possible cure is for this problem. The boat runs fine at higher rpm but when it is in idle, the motor wheezes or coughs and then dies. It will start back up but then the problem occurs again. I also noticed that when I washed the motor out at the landing the motor was able to idle but it sounded "richer" or "heavier" than normal. The boat was serviced within the past 8 months and ran fine before the recent steering cable incident sidelined it for a few weeks. Any suggestions or advice is appreciated. Thank you.
