any way to figure out what belt is on my engine just by a pic??

[turbocorrado]

unfortunately i just realized i never ordered a belt, its pitch black outside right now. its a 4.3 with closed cooling system and a through hull cooling system with the pump mounted on the engine. all i have is the pic of the engine from when i bought the boat 2 weeks ago. does anyone know what belt it is? i tried searching but havent seen a pic with the same setup

Using your serial number you posted a few days ago, you should need Merc part number 57-865615003 that has now superseded to 57-865615Q03 or sierra marine part # 18-15100 (aka 57-8638763) available here on iboats. http://www.iboats.com/Mercury-Marin...1701557--session_id.863649477--view_id.466022

Now knowing all them numbers above, if at all possible, you may be much better off waiting to get the part number directly off of the belt and searching for it online as it could mean the difference between a tight fit to where you would think it is the wrong size belt but with a little technique it will go on or finding the same type belt that should allow you to fully install the belt with room to spare and easily adjust to the proper deflection specifications.

Using the numbers above could go either way for you as there is slight differences in sizes.

Hope this helps, good luck.

or take your old belt to your local NAPA or Carquest and have them match it vs ording it.

Take a pic of the manufacturer's number on the belt and that will get you to a good set of cross references.

Do that and pay half what Merc are asking....
