I have a 2006 YAMAHA 250f four stroke and after a while I hear a annoying squeak kinda like a fan belt of a car. Was curious is anyone else has had the same?
Piece of cake, I had to sign up here just so I could respond to you. Remove the lower unit & your will see the drive shaft. Grease the drive shaft splines with special No. 630-AA or otherwise known at W2 grease. Usually comes in a yellow tube. We have had some of these engines & they were doing the same thing. Our Yamaha rep came in & suggested this as a repair & it worked well. Lack of lubrication. You will most likely fine your issue gone. If it still remains, then check it in with a certified Yamaha repair shop....you have other issues. Andrea
