Does anyone have a cross reference number for a 525 efi serpentine belt. Trying to find an after market manufacture of Mercury's part #57-865615012. Would like to find after market belt B4 I go out and pay big bucks for Mercury's. I'm not CHEAP but why give Mercury all your hard earned money unless you HAVE TOO!!!!

You can go with a Gates, K060883 (88.3" long) belt or a K060888 (88.8" long) belt. The 88.3 is just a touch tight but does work, the 88.8" is basically a direct replacement. You can get it from NAPA or any Gates dealer. You can go with another mfg, but Gates is the best.

Thanks,
Dustin

Thanks Dustin,

When going out on Poker Runs or when STRAYING too far from shore I like carrying a spare. I've been living on the edge the last couple times out.

Yes, its a very cheap spare part thats easy to always carry, should always have 1. Then all you need is zip ties and duct tape, and you'll be able to fix just about anything

Dustin

is it the same for a 500 EFI?

You will need a 88.75 or a 88.76 for that. Whatever it takes

Yes, same belt, 88.8" gates is direct replacement. Gates makes the belts for Mercury.

Thanks Dustin, Picked up a spare today during the oil change stop at NAPA....Geez they are proud of them though $ 37.00 .......ouch but i guess it is most likely the cheapest part I have purchased in a while
