Detachable power unit for self-powered dinghies — The detachable power unit of Evinrude Motor of London, described in the Engineer, February 23, consists essentially (fig. 1) of a single-cylinder, two-stroke M engine with prior compression of the explosive mixture in the crankcase, accompanied by its fuel tank R, a carburettor-mixer, muffler S and ignition system A, including the adjusting lever of the advance is represented in L.

The movement of this motor is communicated to a telescopic shaft T, itself in a protective housing,
also telescopic, and by this shaft to a helix (? ) integral with a meshed angle pinion with a second pinion set on T.
Finally, the group is completed by a circulation pump P, which supplies the water to the engine jacket and by a screw fitting Q, which makes it possible to fix the tank on the aft bulkhead of the canoe.
A lever G, rigidly fixed to the apparatus, is used to direct the propeller and acts, consequently, in the same way as the cradle of an ordinary rudder.

The engine of this group and lubricated by a original way, which consists in introducing the lubricating oil
into the fuel, with which it is driven into the engine housing and from there to contact of to be lubricated.

It does not include any other speed adjustment device other than the lever which acts on the ignition advance.

The power developed by the engine is of about 1.5 horsepower and it turns indifferently
in the direction that is determined by the position of its ignition advance lever L,
