120hp 2.5L OMC 1976, destroys about 2 belts a season. The belt looks too wide to me, and is sitting just above the pulley lips. Took the alt off today and wire brushed some rust out of the pulley, just incase it was causing it to eat the belts. Does anyone know what the correct dimensions of the belt are? Only info I could find was a cross on napa's website of 7/16" wide and 40" long. The one I have is 13/32" wide and 40 5/8" long.

Any help is greatly appreciated. Thanks.
