Default Life Of Serpentine Belt On 525

Mine still looks fine at near 300 hours. Should I replace it as maintenance. Do you guys carry a spare belt?

Replace the belt and keep old one as spare.

Get a new one and keep the old one as a spare, and swap them out each time you switch. I generally do mine each year, not so much that they wear out but being under tension in winter and not moving tends to "form" them.

OK, thanks. Makes sense to replace it and keep the old one as a spare. I do rotate the engine periodically with a socket in the off season so that the same valve springs are not compressed too long. The boat stays indoors and uncovered. I'll get a new belt on there soon. Anyone know the cheapest place to buy one?

I'm just getting around to this as part of my winter maintenance. Does anyone know the NAPA part #? If not I guess I'll just see if they can match it up.
