Mercruiser 120 Harmonic Balancer

[nh3]

I bought a boat w/ a mercruiser 120 that had just come back from the machine shop but not together. After spending the day re-assembling the engine I've come the the crank pulley. I have the hub and pulley but no balancer/damper. Did this engine have one or is it at the previous owners house? Also, does anyone know of a good online parts breakdown of the motor.<br /><br />Thanks,<br />nh3

Thanks, I found a breakdown @doug russell and it shows the same. I had to do a partial install to adjust the valves and didn't want to drive it in and then have to pull it off later to install a missing part. <br /><br />nh3
