Three Belles Marine Parts is the online parts division of Three Belles Marina — a certified Suzuki dealer and full-service marina operating on Smith Cove in Niantic, Connecticut since 2006. We are one of the top five Suzuki oil sellers in the United States.  What makes us different from every other parts listing on the internet: the parts we sell are the parts our certified technicians install, every season, on the boats of hundreds of boaters on the Connecticut shoreline. When you order a Suzuki DF150 oil change kit from us, you’re getting the same kit our service department uses. No guesswork. No compatibility questions. The right parts, the first time.  Our catalog is built around complete maintenance solutions — model-specific kits that include everything your engine needs for an oil change, a water pump service, or a seasonal layup. We do the research so you don’t have to.  We are expanding beyond Suzuki in 2026 — adding Mercury, Yamaha, and Honda to our catalog through our national distributor relationships. If you don’t see your engine yet, check back. It’s coming.
