Quicksilver 897574Q01 Alternator Belt for Mercury 75-115hp EFI Outboards
The Quicksilver 897574Q01 Alternator Belt is one of those small-but-crucial components that keeps your day on the water uninterrupted. When this belt is doing its job, your battery stays charged, your electronics stay alive, and your motor runs with the kind of smooth consistency you count on. Engineered specifically for Mercury 75–115 horsepower EFI FourStroke outboards in the serial number range 1B366823 through 2B094995, this OEM part ensures optimal fitment and performance from the moment it is installed.
The 4-rib Poly V serpentine design provides a wide, secure contact surface that grips the pulley smoothly without squeal or slippage. It transfers power efficiently even when the engine is working hard in choppy water or during fast throttle transitions. Because it is engineered specifically for Mercury EFI outboards, the belt stays properly aligned and tensioned, reducing wear on both the belt and the pulleys over time.
Marine life is demanding on drive belts — heat builds beneath the cowling, salt clings to surfaces, and vibration never really stops. This Quicksilver belt is built with materials designed to withstand that reality, resisting glazing, cracking, and stretching far better than generic aftermarket alternatives. A worn or slipping alternator belt often makes itself known through dimming lights, weaker electronics, or subtle changes in engine sound under load — installing a fresh OEM Quicksilver belt brings everything back into balance.
Suitable for use on a wide variety of vessel types including center consoles, pontoon boats, aluminum fishing rigs, runabouts, and small cruisers. Always verify the engine serial number and confirm belt routing in your service manual before installation. Mercury Marine and Quicksilver products carry a 1-year factory warranty against defects and workmanship.
