Belt help

[mjd99]

my engine serial number is 0D720885. I cannot find the alternator belt and serpentine belt replacement number I need. Can anyone help me with this. Also does anyone know my boats hp based off this? Thanks in advance.

You have a 1992 4.3L, 175hp... (2bbl carb)

The belts are V-belts, part number for the alternator belt is 57-48120A1. But you would be better off going to a local car parts shop and buying an 11A1180 belt, it's the same, and about 1/4 the price.

Thanks Chris! I have the alternator loose and it won’t move enough to get the old belt off.what am I missing?

Remove the bottom bolt completely. That will give you another 1/2" or so of travel. ...
