Where to buy

The Sierra 18-15415 is a cogged V-belt with a 41-1/2 inch effective length and a 29/64 inch top width. It is sold for OMC, Volvo Penta and MerCruiser engines. Its cords are high strength synthetic, built to resist shockload failure. The cogs are shaped to give a large area for air circulation, which keeps the belt cooler, and the rubber edges grip the pulley grooves.

Our take

The 18-15415 has molded cogs shaped for air circulation, and the maker says that keeps heat out of the cushion section. On an engine belt that runs hot, that is a sensible feature, and the 41-1/2 inch effective length is the number to check first.
