Tobias Munthe-Kaas took his first UIM F2 World Championship win at Peso da Régua, heading home Ian Blacker and Owen Jelf on the podium in a Round 4 that reshaped the title race almost beyond recognition.
It was also a landmark for the engine in the back of his boat: the win marked the first time a Mercury Racing 250 APX four-stroke has won a UIM F2 race and stood on the podium, with Blacker’s second-place finish on the same power confirming it was no fluke.
Munthe-Kaas led from the front to take the 20 points, with Blacker second and Jelf completing the podium in third. Bimba Sjöholm, back in World Championship competition after a strong qualifying weekend, took fourth, with Duarte Benavente rounding out the top five.
The race brought turmoil for the championship’s front-runners. Nelson Morin retired early with a power steering issue. Edgaras Riabko, the championship leader coming into the round, was handed a one-lap penalty under UIM Rule 301.01 for missing a turn mark, dropping him to sixth. Giacomo Sacchi received a one-lap penalty of his own, finishing seventh.
The biggest blow of the afternoon came for the title fight itself: Mathilda Wiberg and Peter Morin collided as Wiberg attempted to pass him, ending both of their races. Wiberg was issued a yellow card for dangerous driving under UIM Rule 406.05 in connection with the incident. Hilmer Wiberg also failed to finish.
