Scott,
Shredded belt tip. Pull everything apart at the air plenum down to the butterfly. Those strands get everywhere. Including the cooling vents on the alternator which will suck them further inside. Huge PIA. I run a belt two years then replace it keeping the old one in the boat tool box as a spare. Never had one shred on that program. I also touch the belt up a couple times a year with Prestone belt dressing.
