Design and development

The M25Y is a single-cylinder two-stroke, 173 cc (10.6 cu in) displacement, air-cooled, petrol engine design, with a poly V belt reduction drive. The reduction drive has optional reduction ratios of 2.2:1, 2.3:1, 2.5:1, 2.6:1, 2.7:1 and 2.88:1. The M25Y employs a single capacitor discharge ignition, a WB37 diaphragm carburettor and produces 21 hp (16 kW) at 7900 rpm. The weight is 14.4 kg (31.7 lb) including the exhaust system. [1] [2]

The engine has a centrifugal clutch that stops the propeller spinning when the engine is operated at low RPM, a safety feature for use in powered paraglider applications. [2]

The Pobjoy Niagara is a British seven-cylinder, air-cooled, radial, aero-engine first produced in 1934. The design ran at higher speeds than conventional engines, and used reduction gearing to lower the speed of the propeller. This led to a noticeable off-centre mounting for the propeller. The Niagara was a popular engine for light and experimental aircraft, well regarded due to its small diameter, smooth operation, low noise and innovative engineering.
