John G. Kincaid & Company was a major British marine engine manufacturer based at the mouth of the River Clyde in Greenock, Inverclyde, Scotland.
Its predecessor, Hastie, Kincaid and Donald was founded in 1868[2] by John Hastie, John Kincaid and Robert Donald. It was dissolved in 1871[3] when Hastie left,[2] and reformed as Kincaid, Donald & Co. Robert Donald left in 1881, and the remaining founder, John Kincaid renamed it Kincaid & Co.[2]
The company became limited liability in 1888[2] and was reconstructed as a partnership, John G. Kincaid & Co, between John Kincaid and his brother Charles Kincaid in 1895. The company once again became limited liability in 1906.[2]
