Notes: The design is credited to Niagara Nautic Inc., though in reality, the ONTARIO 28 was one of the first boats designed by Henry Adriaanse after leaving the C&C design team. This helps explain a number of similarities between the ONTARIO 28 and C&C models from the late 1970s and early 1980s.\nWe have seen some information indicating another engine used was the gas powered 30 hp Universal Atomic 4.
