Sierra Marine Serpentine Belt for MerCruiser Engines

The Sierra Marine Serpentine Belt (also called a marine drive belt or accessory drive belt) is built to replace the belt that drives the alternator, power steering pump, water pump, and other accessories on MerCruiser engines. Sierra designs its marine engine parts for the demands of boating, so the belt is made for use around heat, moisture, and constant engine vibration.

Key Features:

• Multi-rib serpentine design drives several engine accessories with one belt
• Constructed for marine duty, with resistance to heat, moisture, oil, and wear
• Engineered to meet or exceed OEM specifications for fit and performance
• Helps keep accessory drive systems turning smoothly and reliably
• Backed by Sierra's long experience in marine engine replacement parts

Replacing a worn, cracked, or glazed belt on schedule helps prevent charging problems, overheating, and loss of power steering on the water. Each belt in this line is made to give dependable service as a direct replacement for the original.
