2026 Volvo Penta V8 SX V8 - 300 hp

Volvo Penta Aquamatic Sterndrive V8-SX is a fully integrated package, powered by the 8-cylinder, 5.3-liter, freshwater-cooled, direct-injected gasoline engine with catalyst. Paired with the well-matched SX single-prop drive, this package provides reduced emission levels and strong acceleration.

Features may include

The compact engine-drive design facilitates installation. With an aluminum cylinder block and head, low-friction, lightweight pistons, and a cast-aluminum oil pan, the engine provides an improved power-to-weight ratio.

The direct injection fuel system enables a high compression ratio, extracting more energy from each drop of fuel. This contributes to reduced fuel consumption and emission levels.

With variable valve timing, the movement of each intake and exhaust valve is adjusted for speed and load. This ensures consistent combustion across varying rpm, contributing to improved torque and acceleration throughout the rpm range.

The freshwater cooling system is designed to extend engine lifespan and improve performance. The closed-loop system prevents seawater exposure inside the engine, reducing corrosion and contributing to improved engine durability and resale value.

With the Easy Drain system, the engine is drained from raw water in just minutes. Thanks to the anti-siphon valve, this is possible with the boat still in the water.

The SX Single prop drive has a lightweight, hydrodynamic design to support improved speed and performance. The durable internal drive train contributes to a longer service life, while the high-capacity through-the-drive exhaust reduces noise and enhances the efficiency of the drive package.
