After 1954, also in '55 the UIM does not award the world title for the 800 kg racers and the same can be said for the continental title of the 2800M cc class. As regards the Italian championships, in '55, we find Flavio Guidotti as the winner in the 1500 cc racers, while in the 2800M his father Liborio succeeds Ezio Selva; the latter wins for the second time, after four years, the fascinating Coppa dell'Oltranza with the new average of 138.581 km/h.

American competitions
At the end of the year and the beginning of '56, Ezio Selva went to Florida to take part in some prestigious events: the mile record day in Hollywood, organized by APBA, the Orange Bowl Regatta in Miami and the "Governor's Cup" in Fort Lauderdale. On December 28, 1955, our champion showed up with his new Moschettiere , built by Timossi and powered by an Alfa Romeo 1500 two-stage compressor, on the timed base built in the narrow Hollywood channel. The initial difficulties, due to the adverse weather conditions caused by rain and strong winds, forced Selva to give up the first of the three planned attempts. A few hours later, with much better weather conditions, Selva launched himself into the second attempt and immediately broke the record! With a speed, in the ascending section, of 139.835 miles/h and in the descending section of 144 and an average of the averages of 141.767 miles/h, our champion conquers the new absolute record on the mile for the 800 kg racers class. The exceptional feat is exalted by the American mass media to which they dedicate extensive reports and giving due recognition to the pilot and his Made in Italy racing car. Selva's record is, as mentioned, recognized by the APBA (American Power Boat Association) for the 800 kg racer class on the basis of the nautical mile; for Europe, however, Franco Castoldi remains the holder of the highest speed on the km, established in 1953 in Sarnico.

From Hollywood Selva goes to Miami where, on January 1, 1956, together with his racer they prepare for the Orange Bowl Regatta. The race is, as always, scheduled over a distance of 3 heats and the final victory is assigned by counting the points of each heat. The competition lives on the duel between the Italian and the very well-prepared American Lauterbach. With a high-school maneuver, Selva overtakes his opponent inside the last buoy, crossing the finish line as winner. Having obtained the victory, for our pilot comes the "cold shower": the jury assigns, in fact, the victory to Lauterbach, claiming that Selva had missed a buoy, which is not true, during the first lap. The buoys made of a single tire, of an American car, and moreover not compliant with the regulations, had already been criticized before the race also by the American pilot Luis Nuta, but for the jury they should not have been modified. After long discussions, the organizers accept the complaint filed by Selva and also by the UIM, admit their mistake, returning the first position to the Italian. Indeed, an additional tire was added to each buoy, and a clearly visible flag was fixed on top. In the second heat Selva was still in the lead: starting from the third initial position he managed to recover and win with a clear lead over Lauterbach. In the third and final leg of the race, when everyone was taking the Italian's victory for granted, bad luck intervened: Selva, after a difficult start, moved from sixth to second position, but despite trying to get closer to Lauterbach, he finished the race behind the American. The spectators, amazed by the performances obtained by the Italian pilot, wondered what had slowed down his very fast Moschettiere . Once the hull was raised, the "corpus delicti" materialized: in fact, it was found that a propeller blade had cracked, probably due to the impact with some debris. This explained why, unfortunately, Selva saw a decrease in engine power on the rev counter.

The Orange Bowl Regatta was awarded to Lauterbach, racing with a hull designed by the engineer Portsmouth of the Hydroplane type powered by a 4500 cc Chevrolet with 3 carburetors. Second place went to Ezio Selva, who can partly console himself in considering himself the moral winner of the race.

On Sunday 8 January 1956, after replacing the engine on the Moschettiere with the spare one, Selva took to the water in Fort Lauderdale for the "Florida Governor's Cup", reserved for racers with 4.5 and 7 litre engines. On a circuit of about a mile and rather narrow, delimited on the sides of the straights by walls with 3 buoys for each turn, ten boats took off over a distance of 8 laps. Selva found himself in a bit of difficulty on the waters that were quite choppy that day and due to the replacement of the propeller that had been damaged in the Miami race: in fact, the propeller was changed to one with a higher pitch that probably could not be considered ideal for that track. With a dazzling start, Stu Wilson took the lead in the race, with George Smith and Selva in second and third place respectively.
Ezio Selva's comeback and in particular his textbook overtaking of Smith are highlighted in the report published in the nautical magazine " Vela e motore", written by Carlo Pagliano who, in addition to being the correspondent, is also present in the capacity of pilot in the outboard class, as well as an observer on behalf of the FIM. Here is a fragment of the article: " ... For a good four laps, competitor Smith, with not very sporting maneuvers, hinders and delays Selva's comeback, who, finally finding a corridor between the walls and this competitor, desperately throws himself into it, managing to overtake him. From the fourth to the sixth lap, the 'Musketeer', daring beyond the limits, skirting the banks, in a truly enthralling duel and with the public thrilled by the intrepid fight, comes alongside the first and on the bend after the finish line manages to overtake him. At that moment competitor Smith is thrown from the hull and ends up in the water outside the circuit..." .
Both Smith and Wilson, both victims of accidents, fortunately only suffered minor bruises, Wilson in particular also suffered a strong shock. Amid general jubilation, Selva flew off to win the race and bring the great "Florida Governor's Cup" to Italy. According to the rules, the cup remains in the possession of the winner for a year, then it is returned to the organizers for a new edition.

The Raid Pavia-Venezia
At the 15th Raid Pavia-Venezia, second consecutive overall victory for Augusto and Camilla Cometti. The Veronese brothers grant the encore by bringing their 3-point Abbate-BPM hull back to success, clocking a time of 4h 11' 10" and an average of 97.224 km/h, also winning the Theo Rossi di Montelera gold cup for the highest speed in the Piacenza-Cremona timed sector, with 126.834 km/h. Behind the winners is the Rivolta-Molli crew (winners of the 1953 edition) on a Timossi-BPM hull
