Hi,
The above motor has done 400 hours and has run like a dream until 12 months ago, it intermittently started to make a whirring/high pitched squeal when I started the motor. I would immediately turn off the motor, even though it was running perfectly and water pump operating with a steady powerful stream, except for the bloody noise. Sometimes the above would reoccur on the second attempt to start the motor or otherwise start without any further problems. The motor would then operate normally for a full days fishing with at least 6 more uneventful "start ups". The problem only seems to occur if I don't start the motor for several days. I took the boat to 2 independent marine mechanics and would you believe, it didn't make the noise on either examination and both stated the motor was operating perfectly. I think they both thought I was nuts. The latter mechanic was the head mechanic at the Yamaha dealer where I purchased the motor new. Even though he stated he couldn't hear a noise or find anything wrong with the timing belt etc. he still chose to replace the timing belt, water pump and completed the full service at a cost of over $700. The problem appeared resolved until about a month ago when the same noise occurred again on starting the motor and going away after the second or third start. It is still happening intermittently!!! please help me boys, because I think I will go nuts if I don't solve this problem.
