Abstract

931,085. Boats' detachable propulsion units. C.A.V. Ltd. Nov. 12, 1959 [Nov. 13, 1958], No. 36501/58. Class 114. In a propulsion mechanism unit for detachable connection to a boat including an internal combustion engine, a propeller rotatable by the engine and means whereby the unit can be moved angularly to steer the boat, the engine is of the compression ignition type having a cylinder block 1 and crank-case 2 arranged to be totally submerged below water level X-X when the mechanism is in normal use. The unit has an upper portion 15 mounted for swivelling movement within a collar 16 pivoted on a bracket 17 clamped to the stem board 18 of the boat, a catch piece 19 being engageable with a pin 20 in the bracket to retain the propeller out of the water when the unit moves angularly in the bracket, and an intermediate portion constituting a fuel tank 9. The upper portion defines two filling necks, one for the fuel tank 9 and the other leading to a tube 27 opening into oil sump 2b in the engine, the tube also serving to admit combustion air to the engine. The exhaust pipe 33 extends into a silencer 34. The outer ends of the blades 4a of the propeller are connected by an annular rim 4b of sufficient mass the cause the propeller to act also as a flywheel for the engine.
