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

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

Compact and muscular, this turbo-diesel marine engine combines V-8 power and packaging. By doing so, this design packs more outright efficiency into every pound and every square foot of engine bay than any “old school” engine.
