The 2027 Yamaha SX180 stands out with a compact, purpose-built profile powered by a Single 4-cylinder, 4-stroke, 1.9 Liter High Output Yamaha Marine Engine that delivers responsive all-around performance in a 17.5 ft hull. Its clean lines and proven powertrain are matched by a practical layout that keeps ballast low and handling precise, making every day on the water feel effortless. Inside, you'll notice thoughtful capacity paired with durable materials designed for real-world use.
