Hamilton Jet Boats

In 1986 Gale Banks continues his marine dominance: The “A309” race boat, powered by a Banks Twin-Turbo 454 and driven by Ken Macdonald, wins the Citizen Watch World Jet Boat Marathon (river race) in New Zealand. The river racing series is the most punishing type of endurance racing imaginable because the 900 hp Banks turbocharged marine engines were constantly shock-loaded and subjected to 7-8g impact loads that can rip the flywheel right off the crankshaft. The engines also have to have a very broad powerband so they can idle down to negotiate shallow waters and then blast off to full power.
