Sierra V-Belt 47-15440
Keep your marine engine running smoothly with this precision-engineered V-belt, designed as a direct replacement for inboard and sterndrive applications. Built to handle the demanding conditions of marine use, this belt delivers reliable power transfer from your engine to accessories like the raw water pump and alternator — the components that keep your cooling system and electrical system working every time you're on the water.
Key Features
- High-strength synthetic cords resist shock-load failure, so the belt holds up under sudden load changes common in marine engines.
- Special rubber compression section ensures smooth, even transfer of load forces to the cords — reducing stress and extending belt life.
- Precision-molded cogs improve flexibility and maintain cord support, while the cog geometry promotes airflow to keep the belt cool and prevent heat buildup.
- Rubber edges maintain positive, no-slip contact with pulley grooves for consistent, reliable drive performance.

Parts Desk Insights
Best use case: This belt is the go-to choice for seasonal maintenance and pre-season engine service on inboard and sterndrive boats. If your raw water pump or alternator belt is showing cracking, glazing, or fraying — or if it's been more than two seasons — this is the replacement to have on hand before you head out. It's also a smart addition to your onboard spares kit for longer passages.
Pair this belt with a raw water pump impeller service for a complete cooling system refresh. See our PCM Impeller Kit RP061017 and PCM / Crusader RP061022 Raw Water Pump Impeller for compatible impeller options. Looking for other belt sizes?
