Yamaha 150 four stroke owners take notice
there is a major failure issue with the harmonic balancer on these in line four strokes. My buddies shop has done well over a hundred but yamaha is not making it a recall issue, dont know why. If you own one get it to your dealer and tell them you noticed a high pitch whine in the motor, the nylon gears are failing. My motor is a 2005 with only 81 hrs but they failed to warranty it, they know there is an issue so I think I will contact the rep with my complaint.
