I have an early ninties Yamaha 90hp outboard. When I change the leg oil, there is always some metal fuzz on the magnetic plug. The motor runs great. Should I be concerned? Does this warrent a rebuild?
 
Thanks Solinsky for yor suggestion. I will give it a try. It runs well as is and would be a shame to tear it down unnecessarily.

Cheers,

William
