It is engineered to OEM quality standards, meaning it is designed to always be correct in fit, form, and function on the applications it covers, so installation is a direct swap without modification.\u003c\/p\u003e\u003cp\u003eThe belt is constructed from high quality polychloroprene rubber combined with polyester fiber tensile members. This combination gives the belt oil resistance and temperature stability as standard features, which helps it hold up under the heat and exposure to fuel and oil residue common in a marine engine compartment. The belt measures 76.5 inches in length and 13\/16 inch in width, and is finished in black.\u003c\/p\u003e\u003cp\u003eThis serpentine belt drives engine-mounted accessories on Mercruiser stern drive setups and is cross-referenced to the OEM part number 57-8638764, so it can be ordered as a direct replacement using either that OEM number or the Sierra part number 18-15101.
