I have tried searching quite a bit, and have not been able to find what the belts are for a HP 500 (carb). Does anyone know this off hand?

I busted a belt last run of last season, time to do them all.

I have a 99 if that matters.

I'm assuming this would be in the owners manual (on my boat in storage.....)?

Take them to a NAPA or a real parts sore and have them match them up. Go goodyear gatorback if you can but any will do. No diff than what merc put on and a lot cheaper(:

The pump drive belt must be a true V belt without the teeth. The tensioner will make it split.

Boats up in a rack and I'm planning to have the labor done there but provide the parts.....may just be worth it to have them pick up the belts.

I think they said $100 for them at the end of last year and it felt steep to me.

Probably 10 to 15 a piece at part store.

That's what I was figuring too.....

Do you have your engine serial number handy?

OL60025

There's a way to find from that?

Thanks

Yes, using the engine serial number is the best way to find the correct Mercruiser part numbers for your engine or drive system.

Also just as a FYI the serial number you posted is missing one number at the end, There should be a "0L" then there should be six numbers after it to find your engine, especially with your engine because it would mean the difference between having a Carbed engine or a EFI engine if your off one number.

From what I can tell from the serial number you posted and me guessing a final number, Your engine does not have Power steering?

Merc part number 816034 is Superseded to 816034Q $42.78 Description: V BELT, 48.125 LG (Water Pump)

Merc part number 812427T is Superseded to 812427Q, MSRP: $47.90 Description: V BELT, 56 LGTH (If you have "Power Steering")

Merc part number 69143T is Superseded to 69143Q MSRP: $27.30 Description: V BELT, 40 LGTH (Sea Water Pump).

And here is a link to all of your engine parts for you.
