In November, 1897, Mr. James Livesey Scott and his son Ernest commenced work at Mannum, South Australia. They worked on Paddle Steamers, in the dry dock where today the P.S. Marion rests. In addition to this, Mr. Scott had an agency for imported stationary engines and pumps which he sold along the River Murray.

Directly opposite the dry dock, Mr. Scott rented a building in which, in 1905, Mr. Em Scott designed a stationary engine and centrifugal pump, patent No. 5473. The factory had its own brass foundry, but all the iron castings were done in Adelaide by Stewart & Harley. Otherwise the design, pattern making, machining and fitting were done in the Mannum workshop by a team of very capable tradesmen.

All the Scott engines were of the vertical, 2 stroke type, available in 8, 5, 3, and 1? HP ratings. The 8 HP was mainly used for driving pumps and for normal farm work such as driving chaff cutters or saw benches. The 5 HP Scott engine and centrifugal pump were built onto a cast iron base and were always sold as a pumping unit. It weighed approximately ? ton. The engine was directly coupled up to the pump by an over-center cone clutch.

The 3 HP was mainly used as a marine engine, but some were used on farms to drive machinery. The 1? HP engines were air-cooled and were used on all kinds of small jobs on the farm.

Mr. Ern Scott fitted one of his 3 HP engines to a Sunshine harvester to drive the drum and winnower. For this achievement he applied for a patent. This resulted in Mr. Scott being the first person in Australia to apply for a patent for a motor to be used on a harvester.
