Although a bit of a misnomer as the boats aren't without limits, unlimited hydroplanes have much fewer restrictions than with limited hydroplane racing. These 30 foot, 6,800 lbs boats most often powered by a Lycoming T55 -L7 turbine engine (used from the Vietnam era to the present day in the CH-47 Chinook military helicopter ), which is capable ...
The result was a 502 bhp speedboat, which he used to hit a 150.19 mph top speed in October 1953 on Lake Iseo. This world speed record for an 800 kg boat still stands today. [3] A similar hydroplane was constructed by Guido Monzino in 1954. Like Arno XI, it utilizes a Lampredi engine, in this case sourced from a wrecked Ferrari 375 MM. [4]
