Recruited from Federal League side Mordialloc, McMahen had the choice of four league clubs. With his childhood heroes Richmond not interested McMahen leant towards Hawthorn before eventually plumping for the Demons after secretary Jack Chessell worked hard to convince McMahen and his family that they were the right side for him.
Breaking into the team midway through the 1946 season, McMahen was forced to miss the rest of the year after an attack of Bell's Palsy. He played in the 1948 premiership but by 1949 was back in the reserves, where he played in another flag. Disgruntled with not being considered a first team player he accepted a job as Captain-Coach of Camberwell in the VFA but was talked out of taking it up by ex-player Francis Vine.
In his early days he was tried in several different positions - ruck, full forward, defence and on the wing until finally finding a permanent spot on the half-back flank in 1950. It was then that he broke into the senior team permanently, winning. the 1951 Best and Fairest and playing for Victoria in 1952.
He was appointed vice-captain in 1953, and after playing through much of 1954 with an injury he was promoted to captain in 1955 after incumbent Geoff Collins left to join Heyfield. That year he led the premiership side and was selected on a half back flank in the Sporting Life "Team of the Year". Lucrative coaching offers flooded in from around the league and country, but McMahen decided to stay on another year. It was a wise decision, as he captained another premiership.
After announcing midway through 1956 that the season would be his last before he joined the coaching ranks, McMahen joined Rochester for 1957. He turned back lucrative officers from WA, Tasmania, other VFL clubs and the VFA, leading his side to Bendigo League premierships in 1958 and 1959.
He served on the club committee from 1969 to 1973 before losing a re-election bid while serving as chairman of selectors. McMahen returned to Melbourne to sit on the executive in the late 1970's. He returned again in 1991 as Deputy Chairman to Ian Ridley and Finance Director before resigning in February 1995.
Football Record 1947 states he simply 'returned to Mordialloc' with no mention of Bells Palsy.
