  • Yamaha '89 30hp idle problem

    The motor runs good but sometimes has problems with idleing down low. Sometimes i can back the throttle all the way down and it will purr just fine and other times it will cut off. Sometimes running the boat for 30 min or so will help but rarely can I back it all the way down (in neutral or in gear). Also theres a certain point on the trottle, probably a little less than half throttle, if I slowly ease up on the throttle before i plane off the motor will kinda stutter a little bit but if i increase throttle it stops. Its almost like it cuts out 1 of the 3 cylinders and then it kicks back in.. Any ideas...
