The photo to the right is the only piece of a Knight of which I have a picture! It was found on a rubbish pile next to a derelict croft in the Western Highlands of Scotland some 20 years ago. Thanks to Peter Freshwater saving this relic we now know the Knight was a badge motor made by Archimedes for Knight, or perhaps produced under their patent in Great Britain.

  A large number of users are now adopting small motors of the outboard type owing to the price of marine motors in general. Outboard users are fitting them to dinghies and small boats for which they are.very well- adapted. The ordinary outboard motor has a single cylinder,but some of the newer designs are now being fitted with two cylinders, one of the examples of this class being illustrated in Fig. 3. 

This is a twin opposed cylinder engine developing 3_to 4 hp. It is known as the Knight engine, sold by theKnight Outboard Co. of Hampton Wick, Middlesex, at a price of under £50 complete.

Apart from the fact that two cylinders are fitted, it operates on the same general principle as the average outboard motor , such as the Evinrude type, working on the two-cycle principle. Another motor of somewhat similar design with two horizontal cylinders but of American manufacture is the Koban which is sold in England at £45. It is claimed for the two-cylinder t y p e that the vibration which is always noticeable with an outboard motor is very greatly diminished, and it must be admitted that there is some improvement in this respect.

The demand for these outboard motors at the present time is so large that it is difficult to obtain deliveries especially in view of the present restricted output and the trouble which was encountered as a result of the prolonged moulders' strike which had an effect on the marine motor industry as much as on the motor-car business.
