Berkeley has been manufacturing pumps of many kinds since 1937. The Berkeley Jet Drive was introduced in 1960, and many thousands have been supplied to the boating public since then. Today Berkeley offers four 12J drives, each a little different but incorporating essentially the same basic features and using, where possible, many of the same parts for interchangeability.
