557 supercharged horsepower.
Outboards to the power of seven.
Start with a fuel injected marinized 6.2L supercharged small-block V8, managed by GM’s powerful MEFI 6 engine controller. Then put out 557 horsepower at the prop shaft and one word comes to mind… MUSCLE. General Motors’ LSA has nearly six decades of continuous development behind it and 100,000,000 small blocks later, it’s ready for a whole new application – the outboard motor. Running on 89 octane fuel, no premium required, whether fishing offshore, running to the Bahamas or powering a new tender, the 557 is ready. Flexing so much outboard muscle under one cowl has never been possible –until now.
