Hello All,

First post here, I just recently bought a 2011 Sea Ray with a mercruiser 4.3 TKS. The last time I took it out, the belt fell off. I reinstalled the belt and cranked it back up. I noticed a wobble on the crank pulley. It doesn't sound like it is running rough, I'm just looking for possible issues that it could be.

Thanks

Check to see the bolts (item 13) holding the pulley on are still there and are tight.

Bondo, the pulley faces are not rusted.

AllDodge, I checked the bolts and they are tight. I'm thinking it's the harmonic balancer.

Take a straight edge and see if the pulley aligns up with the others
