Oversized belt
by Enrique from Hamilton, Ohio on May 28, 2015
It fits on my 91 OMC engine alternator, but I believe the belt is too wide for the type of pulley my alternator and engine has. It actually rides partially on the pulley flange rather than the groove. Not sure if this is normal or a little oversized. It did fine my first trip out on the water.

by Bradford from Alexandria, Virginia on June 12, 2012
A must for any one on the water. Got 3 all brand new, not old inventory that has been laying around. Also fast shipping a real bonus.
