This is the Sierra 18-15490 V-belt, a replacement for MerCruiser sterndrives. It measures 52-1/2 inches in effective length with a top width of 29/64 inch. It is built with high strength synthetic cords to resist shock load failure, and low stretch is meant to keep performance uniform through the belt's life.
Our take
A 52-1/2 inch effective length and 29/64 inch top width pin down the size of the 18-15490, so measure your old belt first. Synthetic cords resist shock loads, and low stretch is meant to keep tension even over its life.
