Well always something right ! - my serpentine belt came apart and is not readily available I guess. According to merc it looks like its absolute and is now part # ( 57861049Q ) number off he belt that came apart is ( 57861049-1DF ) showing a price of $80, anyone know where I can pick it up, or have shipped pretty quick?,spouse to go back out Thursday but if I can't I can't !!

Thanks again guys -

Measure it and cross ref. Length by width. Gates or Goodyear must make it...

I'll try that - Orileys didn't have it and all the stores near by where closed !

Thanks for the tip!

Give me the year and model of your motor and I will try to get you a napa number.

Rick take a string and go around the belt with it exactly ( if the belt belt is not broken in half ), then cut the string were the two ends meet. Lay the string straight on the ground and measure it in inches and mm's. A lot of belt manufacturers cross by mm lengths. Gates, Dayco, Goodyear and so on. I match these up all the time that way.

Just did a 496 that the had the pulleys changed out with some mods and it was not the standard Mercruiser length. Anyways this is how I match them all the time. Some are not the exact same size but maybe 2 mm off, that still will work all day long. Some are the exact size.

I just checked for you and retail is showing 94.70 thru merc. Also Sierra is 18-15114

I can check availability on them if you want - if available I can get them next day. Some shipping charges might apply because of a small order thru Merc or Sierra.

just making sure 57861049Q is the part # you are looking for - correct ?

Thanks BUP - the number on my broken belt is ( 57861049-1DF) per merc it's is obsolete and the new number is 57861049Q I guess!

Thanks for the help - really appreciate it !!

Thanks for the assistance !!
I'm not sure the year- its a 502 mag if that helps !

I found the belt for 75 threw merc buts it doesn't ship for 5-7 days then another who knows how many days after that - ill measure it tomorrow and post it !

You guys are awesome- truly appreciate the help, and sorry for the late response - had to take a group of guys out bowfishing, at least that boat didn't have any problems !!

it wont be Merc shipping it directly to you - its thru a dealer or boats,net or someone like that. Sometimes it takes 2 weeks to get your door from companies like boats.net. Just measure it in both inches and mm and go to the auto parts store. Its cheaper also.
