350 mpi Serp. Belt

[goose69]

I have a 2003 350 MPI tow sport mercruiser motor and my serp. belt looks like it needs changing. Does any one know the belt number? can you get at an autoparts store?

I would think they would be able to match it up to something at an autoparts store.

i didn't want to take it off til i got a new one.

Sorry, I am no help then.

I took mine off went into the local checker auto parts store and they all usually have a stick that measures belts and can match it up got me a new one. Just draw or take a picture of the current belt routing if you are worried you wont remember it I had mine off for almost a month and it took me a few minutes to figure it out.

just snap a quick pic with your cell phone before taking it off so that you know how it goes on....take it off and go to an auto parts store.....it is very easy to change it out.

2000 2100 V Limited with Merc 350 MAG MPI Ski. I'm on my second "Gatorback Poly-V" The package showed two numbers that I made note of after the first buy: 4060875 and 6PK2225. I bought both at Autozone and have been very satisfied. Good luck

Taking the belt off is LITERALLY a one minute job. Super easy. Getting the new one fed back on the proper wy takes a little bit longer, but still not a big deal. I changed my first one ever in about 15 minutes and I feel comfortable saying I could do the next one in under five minutes.

Thanks Jason & wakemaker,

I updated my Winterization sheet w/ more p/n's that I didn't have. If anyone has p/n's that Jason didn't post, please post them. My sheet right now is for an older model Mercruiser 350 MPI/EFI engine.

I will also through this out there, If some has a different engine and has P/N's for items on that engine you can email me and I will add another sheet to my excel file for that engine. Right now Tige should have 3 or 4 engine sizes correct?

Thanks

I'll get it to you Tuesday though..
