The 2027 Yamaha AR205 immediately stands out with its Single Supercharged 4-cylinder, 4-stroke, Super Vortex High Output Yamaha Marine Engine, delivering propulsion that's built for confident days on the water. This powerboat pairs a beamy 8.5 ft hull with a 20.08 ft length, creating a stable platform for family trips and spirited runs alike. With a dry weight of 3070 lbs, it carries a robust structure while maintaining responsive handling behind the helm. Inside, practical capacity and storage define the experience. The vessel accommodates up to 10 people and offers a generous 502 gal of storage capacity, so essentials stay neatly stowed no matter the adventure. A 40 gal fuel tank keeps you afloat longer between fills, while a 1.58 ft draft and a 20 degree dead rise contribute to efficient planing and early, stable planning on wake-friendly waters. The engine's 1812 cc displacement underlines responsive acceleration, and premium unleaded fuel keeps performance aligned with premium expectations. The beam measures 8.5 ft, delivering a roomy cockpit and ample space for lounging, spare gear, or picnic setups. Strength and capability go hand in hand with refined build quality. The overall weight capacity reaches 1900 lbs, ensuring crew, gear, and daily usage stay within recommended limits. The Yamaha AR205 is crafted for moments that blend quiet lakeside mornings with high-speed lake days, where precise control and dependable power define the ride. Experience the fusion of engineering and practicality that makes every outing feel purpose-built. View the Yamaha AR205 at Vallely Sport & Marine.
