Volvo Penta V8-300-C SX Aquamatic Gasoline Sterndrive Engine

The Volvo Penta Aquamatic V8-300-C SX is an integrated sterndrive package with a 5.3-liter, 8-cylinder direct-injection gasoline engine, a catalyst and broadband oxygen sensors, paired with a single-propeller SX drive. It is freshwater cooled.

The engine's aluminum cylinder block and head, lightweight low-friction pistons and cast-aluminum oil pan keep the engine-and-drive unit compact for easier installation. Direct spark-ignition injection allows a high compression ratio, while variable valve timing adapts the valve events to speed and load throughout the rev range.

A closed freshwater cooling circuit keeps seawater away from the engine internals to resist corrosion. Easy Drain clears the raw-water side in a few minutes, and the anti-siphon valve makes this possible afloat. Electronic engine control, a lightweight aluminum exhaust, an integrated kick-up function and easy-access service points are built into the package.
