I have a 2000 Yamaha F40 Manual trim and start and have a few questions that I havent been able to get satisfactory answers from my dealer over the phone (but I havent brought it in). The motor is still under warranty and has 180 hours on it. Ive read through the forum and searched the archives, and found a lot of good related info, but nothing specific to my questions.<br /><br />Timing belt
according to the owners and service manual my belt is loose. The service manual says that it should have 1 cm of play and it easily has 2-3 cm of play in the area where they say to test (the other side is much tighter). I talked to my dealer and they said that they have never changed a timing belt on a Yamaha F-anything. I find this hard to believe, given that I see on this forum that the recommended life is 1000 hours. I only have 180 hours on this motor, although it is several years old. The belt looks beautiful to me in terms of wear. Is this a problem? Would this repair be a warranty repair (I still have 4 months on the warranty)? If not, is it easy to do, and is there an aftermarket manual to get (since there is no way I would be able to do it based on the service manual I have)? <br /><br />Second question
I have an intermittent noise that only occurs when the motor is warmed up, but does not always occur when the motor is warm and is noticeable at idle and mid throttle (I dont know if it goes away or is covered up by motor noise). It more commonly starts after the motor is restarted, rather then just while running, although it does just begin at times. The sound is Swish, swish, swish, not a squeal like a slipping belt, but it has a squeaking quality. It is obviously tied to the RPM of the motor and at idle is noticeably swish, swish, swish, but turns into more of a whine or squeaky sound at higher RPMs. Ive never been able to have it make the sound under conditions where I could really study where it is coming from, although in a day of fishing and shutting the motor off and on many times, and running at both WOT and idle it would likely appear once.<br /><br />Thanks,<br /><br />Tod
