As for Ismailciuc himself, realising he could not match fellow Dinamo canoeist Leon Rotman’s times in the singles events, he looked for a partner among the young people he had selected, and he chose Dumitru Alexe. The two of them competed in the C-2 events in the 1956 Summer Olympics. Some liver complaints by Ismailciuc prevented them being placed higher than fifth in the C-2 10000 m event. However, they competed brilliantly in the C-2 1000 m event, where they won Olympic gold. They went on to become European champions in Ghent, Belgium (1957) in the C-2 10000 m event (they won silver in the C-2 1000 m event). The bronze medal in C-2 10000 m was won by two of Ismailciuc’s protégés (Ichim Lipalit-Lavrente Calinov), as one country was entitled to two entries in each event. At the 1958 World Championships in Prague, Ismailciuc and Alexe won the gold in the C-2 1000 m event. Deserted by Alexe, who retired and returned to his previous job, Ismailciuc tried his luck in the C-1 1000 m event for the 1960 Summer Olympics, he was already credited with better results than reigning Olympic champion Leon Rotman. However, Romanian coaches were unable to decide between the two, so both were part of the Romanian Olympic delegation in Rome. The on-site test races on Lake Albano showed Rotman was faster and allowed to represent Romania at those games. Ismailciuc retired as a result of his second-place finish though he would return to win a gold in the C-1 1000 m event at the 1963 World Championships in Jajce.
