Flex Some Muscle

The 565 sterndrive combines the proven performance of big block power with the creature comforts of digital throttle and shift. A stroked, 8.7 liter cylinder block combined with high-performance cylinder heads, multiport fuel injection and twin electronic throttle bodies results in a whopping 565 horsepower that’s sure to blow your hair back. This power comes from 89 posted octane fuel; making this naturally aspirated powerhouse a natural for high performance vee bottoms and catamarans as well as sport cruisers.
