The 2027 Yamaha SX180 stands out with its responsive single 4-cylinder, 4-stroke, 1.9 Liter High Output Yamaha Marine Engine delivering efficient power in a compact, 17.5 ft hull. Its clean, accessible layout pairs premium materials with precise build quality, making this powerboat feel refined from bow to stern. With a dry weight of 2150 lbs and a frame designed for stability, this model invites weekend sailors to glide onto the water with confidence while keeping fuel efficiency in mind for longer deployments. In terms of capability, the SX180 carries a maximum weight of 1375 lbs and supports up to 6 persons, while the 7.5 ft beam provides a broad, steady platform. The 30 gal fuel tank keeps outings self-sufficient, and the 1.33 ft draft lets you explore shallow coves and coastal shallows with ease. A notable 18.5 degrees of dead rise contributes to smooth handling in chop, and the 200 gal storage capacity ensures ample space for gear and essentials. Regular unleaded is recommended, making refueling straightforward for both weekend adventures and longer day trips. In everyday use, the Yamaha SX180 blends compact maneuverability with practical living space, inviting you to pack lights and glide to your favorite waterfront destinations. The 17.5 ft body length strikes a balance between nimble docking and comfortable on-water presence, while the engine's quiet, reliable performance keeps your focus on the scenery rather than the machinery.
