The Gurkha was developed as a replacement for the Mohawk with a bore of 100 mm (3.94in) and the gear ratio was reduced to 1.86:1, giving 240 hp (179 kW) at 2000 rpm. Production ended in
October 1916, after 74 units had been supplied to power the Short 184 seaplanes of the Royal Naval Air

Initial version of the V-12 Mohawk built with 80mm (3.15in) bore, developing 200 hp (149 kW). The
Admiralty required more powerful engines than the Crusader, so Coatalen designed the Sunbeam 225 hp (168 kW) as a 60 degree V-12 using blocks of three cylinders instead of the

until the
Sunbeam naming system labelled it the Crusader in 1917. The 80mm bore versions were produced in limited numbers, mostly for civil use, but later 90mm bore engines had limited success in civil applications, with more than 226 built for military aircraft.

Outwardly identical to the
Crusader, the Zulu was developed during 1915, the bore was increased from 90 mm to 100 mm and the reduction gear ratio was changed to 1.86:1, allowing the engine to develop 160 hp (119 kW) at 2000 rpm. 75 Zulus were

Production versions built with 90mm (3.5in) bore, rated at 225 hp (168 kW). Short seaplanes using this engine were often called "225s". During 1917 this engine was re-named as the

Introduced late in 1914, the 90mm (3.5in) bore versions were referred to as the 150hp and could be rated at 135 hp (101 kW) or 150 hp (112 kW).
