In 1967 Ferruccio Lamborghini bought a Riva Super Aquarama and, without hesitation, replaced its stock V8s with two 3.5-litre V12s harvested from the 350 GT. The pair delivered roughly 700 CV and pushed the sleek launch craft to almost 50 knots (about 93 km/h). This bold swap proved that a supercar heart could survive the harsh marine environment and sparked the idea of a dedicated line of racing V12s for offshore competition.
From Yacht Experiment to Dedicated Marine Engine – the 1980s
The first purpose-built unit arrived in 1982 as the model 804. It featured an 8.0-litre aluminium block, a 60° V-angle and weighed just 398 kg, while producing 720 CV. Two years later, Italian racer Alberto Petri bought a 38-foot monohull from CUV di Viareggio installed twin 804s and christened the boat “Miura”. Competing in the UIM World Championship the Miura seized the title on its very debut in 1984, confirming the viability of Lamborghini’s marine philosophy.
Technical Leap – the L804 V4 and L900 Variants
By 1987 the program had evolved into the L804 V4. Its displacement grew to 8.2 litres, and the engine adopted a four-cam-per-bank layout with four valves per cylinder, delivering 880 CV. Despite sharing the same V-12 architecture as road models, none of the components were interchangeable; every part was re-engineered to survive salt-water corrosion and sustained high-load operation.
Parallel development yielded the L900 a 9.3-litre powerhouse intended for luxury yachts. Instead of electronic fuel injection, it relied on carburettors, limiting output to 770 CV but favouring long-term reliability—a priority for owners who valued durability over outright speed.
Luxury Meets Speed – the Quetzal Series
Also in 1984 Lamborghini introduced the Axess Quetzal a custom-built 38-foot racer equipped with two modified, carburetted V12s. The boat could hit 65 knots and featured opulent interiors of wood and leather. Its sibling, the Masha Quetzal sported an aluminium hull and entered the Classe 1 offshore circuit, where the brand’s marine engines began a rapid evolution from mechanical to electronic fuel injection. By the early 1990s the power output topped 1 440 CV propelling hulls to the benchmark 80 knots (approximately 150 km/h).
The Golden Era of the 1990s – Dominance and Legends
Offshore racing in the 1990s demanded not only raw power but also iron-clad reliability, as engines ran at full throttle for minutes while battling salty cooling water and relentless hull vibrations. Lamborghini’s marine V12s excelled in this arena. Boats such as Spirit of NorwayVictory and the Giesse Philosophy repeatedly topped podiums. Piloted by Norberto Ferretti and Luca Ferrari the Giesse Philosophy clinched the 1994 UIM World Championship adding to a total of 88 victories across national, European and world titles.
One of the most eye-catching machines was the Fast 45 Diablo a one-off created at the founder’s request to showcase Lamborghini’s racing propulsion. Its bright yellow livery and signature “airscoops” made it an instant icon of the Classe 1 spectacle.
Formula 1 Drivers on the Water
The allure of Lamborghini’s marine power even reached the world of Formula 1. The tragic loss of Didier Pironi occurred in 1987 during a race off the Isola di Wight underscoring the extreme risks of offshore competition. A few years later, in the summer of 1993, Ayrton Senna took a test run in the carbon-fiber Giesse Ferretti. The twin V12s produced a combined 1 800 CV propelling the craft to a recorded 212 km/h and offering the Formula 1 champion a taste of marine adrenaline.
Across two decades, Lamborghini transformed a celebrated road-car engine into a marine legend, proving that the same V-12 formula could dominate both asphalt and open sea.
