Westbury Kittiwake 15cc OHV Model Tether Boat Engine by Edgar T. Westbury, UK, 1936

This 15cc 4-cycle engine measures 6 inches wide, 7.5 inches high, 5.5 inches long, weighs about 4 pounds and is designed to burn gasoline on spark ignition. The crankshaft provides splash lubrication for the internal parts, however there is an oil pump that circulates oil to and from the crankcase. Normally the oil pump was used to lubricate a front sleeve bearing, however, this engine sports ball bearings for the crankshaft that are lubricated by the crankcase oil.

 

Red and yellow brass was used to make the water jacket as well as many other components in the engine. The crankcase, connecting rod, piston, head, valve cover, carburetor body, and float bowl are aluminum castings. The crankshaft, cam, and flywheel are machined from steel bar stock.
