Banks legendary performance reputation was first earned in the high-performance marine engine business in the '60s'. Since that time world, national, state, and local speed and endurance records have all fallen to Gale Banks Marine Engines-equipped boats.

Now, applying the same engineering expertise that motivates the 1,200-horsepower Duramax 6.6L V-8 in their record-setting drag racing, and land speed record competition vehicles, Gale Banks Marine Engines has built the ultimate, fully-marinized, Duramax based advenced technology engine.

Compact and muscular, this twin-turbo engine combines V-8 power and packaging in a design that packs more outright efficiency into every pound and every square foot of engine bay than any "old school" engine.
