Turbocharged, inter-cooled and featuring two-stage fuel injectors, the Steyr marine diesel builds more horsepower per cubic inch than ought to be legal. At the same time, it sips fuel at a miserly rate. Best of all: Atypical for a diesel, it's not particularly heavy, thanks to its high alloy, lightweight castings. Other good news, smoke and fumes are virtually nonexistent.The engine mates to a wide variety of transmissions, including direct-drive, horizontal, eight-degree down angle and 12-degree V-drive. It's also an appropriate choice for the MerCruiser Bravo drive leg.
