Purchased as a yearling by prominent owner/breeder Larkin Maloney, Ace Marine was trained by Canadian Hall of Fame trainer Yonnie Starr.
At age two, the colt won two races and was a strong third to the then world-record-holding sprinter Boston Doge in the Newport Stakes at Narragansett Park in Pawtucket, Rhode Island.
Ace Marine's performances earned him Canadian Horse of the Year honors.
Returning to race as a four-year-old in 1956, Ace Marine won the inaugural edition of the Canadian Maturity and the important Dominion Day Handicap.
Ace Marine was retired to stud having won fourteen races, but as a sire met with only modest success.
