The only boat to ever be powered by a Ferrari engine, which set a world speed record on water in the 1950s, is set to go up for auction in Florida.
Built in 1952 the Ferrari Arno XI, which was previously valued at £1.5million, was made for the 800kg class and contains a modified Grand Prix 4.5L V12 engine which can push out more than 550 horsepower.
Italian speedboat racer Achille Castoldi was determined to break the world record for racing the fastest boat and turned to Enzo Ferrari for help in powering a hydroplane.
Enzo and Castoldi built the only Ferrari-powered boat ever made with its upper body painted in Ferrari’s signature red colour.

This was paired with a three-point hydroplane constructed from hardwood with a mahogany veneer finish.
An impressive, modified Grand Prix 4.5L V12 which pushes out more than 550 horsepower powered the boat, allowing the Arno XI to reach a top speed of 150.49 mph on water.
This record speed was recorded on Lake Iseo, also known as Sebino, in Italy, and it has yet to be broken.
The engine used was identical to the 385 horsepower Lampredi engine, which was named after the Formula 1 team’s then technical director, used in the race car Ferrari 375.
Enzo also sent his Chief Engineer Stefano Meazza and some of the Scuderia Ferrari crew members to help make the hydroplane boat faster.
