    Yamaha Harmonic Balancer

    Just an FYI for anyone who owns a mid 2000’s Yamaha F150. I learned the hard way that if you do not replace the balancer, the original in the motor is a ticking time bomb. There is a ton of threads that point this lemon out but of course I didn’t see them until mine went bad. Long story short, the balancer is made of nylon parts and they can disintegrate, pass through the power head. By the time the low oil pressure alarm goes off, it’s too late and is catastrophic. I only had 260hrs on the motor. $700 part vs new motor or power head.
