An outboard motor is a propulsion system for boats, consisting of a self-contained unit that includes engine, gearbox and propeller or jet drive, designed to be affixed to the outside of the transom. They are the most common motorised method of propelling small watercraft. As well as providing propulsion, outboards provide steering control, as they are designed to pivot over their mountings and thus control the direction of thrust. The skeg also acts as a rudder when the engine is not running. Unlike inboard motors, outboard motors can be easily removed for storage or repairs.
The Bristol Mercury is a British nine-cylinder, air-cooled, single-row, piston radial engine. Designed by Roy Fedden of the Bristol Aeroplane Company it was used to power both civil and military aircraft of the 1930s and 1940s. Developed from the earlier Jupiter engine, later variants could produce 800 horsepower (600 kW) from its capacity of 1,500 cubic inches by use of a geared supercharger.
The Ryan Aeronautical Company was founded by T. Claude Ryan in San Diego, California, in 1934. It became part of Teledyne in 1969, and of Northrop Grumman when the latter company purchased Ryan in 1999. Ryan built several historically and technically significant aircraft, including four innovative V/STOL designs, but its most successful production aircraft was the Ryan Firebee line of unmanned drones used as target drones and unmanned air vehicles.
Superkart is a form of motorsport road racing that uses karts on long circuits. The bigger difference between a superkart and most other forms of kart is that they have full aerodynamic bodykits, as well as having a longer wheel base than sprint chassis, and are generally raced on car circuits over 1,500 metres in length. The power unit, most often but not exclusively two-stroke 250 cc engines, can be specially designed kart engines or production motorcycle engines with either five- or six-speed sequential manual gearboxes. Owing to their high top speed and superb cornering ability, a superkart's aerodynamic bodywork includes a front fairing, larger sidepods, and a rear wing. They use either 130-or-150-millimetre-diameter tires and wheels and most often race on full size auto-racing circuits.
The Yamaha Virago 535 is a motorcycle manufactured by Yamaha Motor Corporation. It is one of several in the Virago line and is positioned as mid-size cruiser with an engine displacement of 535 cc (32.6 cu in).
The Toyota A Series engines are a family of inline-four internal combustion engines with displacement from 1.3 L to 1.8 L produced by Toyota Motor Corporation. The series has cast iron engine blocks and aluminum cylinder heads. To make the engine as short as possible, the cylinders are siamesed.
The Yamaha Virago was Yamaha's first V-twin cruiser motorcycle, and one of the earliest mass-produced motorcycles with a mono-shock rear suspension. Originally sold with a 750 cc (46 cu in) engine in 1981, Yamaha soon added 500 cc (31 cu in) and 920 cubic centimetres (56 cu in) versions.
The SR engine is a series of 1.6 L (1,596 cc), 1.8 L (1,838 cc) or 2.0 L (1,998 cc) straight-four, four-stroke gasoline engines manufactured by Nissan. It has an aluminium head and block with steel sleeves and has a DOHC 4-valve design, with variable valve timing on select models. It was added to a new engine family name PLASMA.
A multi-valve or multivalve engine is one where each cylinder has more than two valves. A multi-valve engine has better breathing, and with more smaller valves may be able to operate at higher revolutions per minute (RPM) than a two-valve engine, delivering more power.
The Toyota R family was a series of inline-four gasoline automobile engines. Designed for longitudinal placement in such vehicles as the Celica and Hilux and in production from 1953 through 1997, usage faded out as many of Toyota's mainstream models moved to front-wheel drive. Overhead cam (OHC) versions featured a chain-driven camshaft.
The Ford Sigma is a small straight four automobile engine introduced in 1995 by Ford Motor Company. Its first evolution was sold as the Zetec-S, then Zetec-SE and finally, in later years, renamed Duratec. The last upgrade of the engine is named Duratec Ti-VCT. Conceived for Ford's smaller models, the motor was intended to replace the older HCS and smaller capacity CVH units.
The Wright R-975 Whirlwind was a series of nine-cylinder air-cooled radial aircraft engines built by the Wright Aeronautical division of Curtiss-Wright. These engines had a displacement of about 975 cu in (15.98 L) and power ratings of 300–450 hp (220–340 kW). They were the largest members of the Wright Whirlwind engine family to be produced commercially, and they were also the most numerous.
The Yamaha YZ450F is a four-stroke racing motocross bike built by Yamaha Motor Corporation. It was the successor to the previous YZ426F which was discontinued in 2003. It is credited by Cycle World and Dirt Rider magazines as the bike that started the four-stroke dirt bike revolution. The 2006 YZ250F and YZ450F were the first production motorcycles equipped with titanium suspension springs.
The Kaman K-225 is an American experimental helicopter developed by Kaman Aircraft. One example was modified to become the world's first gas turbine-powered helicopter.
The Yamaha Aerox is a lineup of single-cylinder scooters made by Yamaha since 1997, available in either 50 cc or 100 cc for the European market, and 125 cc or 155 cc for the Southeast Asian market with several different body designs.
The Subaru FB engine is the third generation of gasoline boxer-4 engine used in Subaru automobiles, and was announced on 23 September 2010. It follows the previous generation EJ-series engine which was introduced in 1989 and the first generation EA-series which was introduced in 1966. By increasing piston stroke and decreasing piston bore, Subaru aimed to reduce emissions and improve fuel economy, while increasing and broadening torque output compared to the EJ-series.
The Yamaha YZF-R7 is a super sport motorcycle based on the MT-07 platform. On May 18, 2021 Yamaha announced the motorcycle, sharing a name with the 1999 YZF-R7 race homologation bike. The 2022 motorcycle is a mid capacity powered by a 54.7 kW (73 hp) liquid cooled four-stroke inline two cylinder double overhead cam 689cc engine. It features forged aluminum pistons with direct plated cylinders integrated with the crankcase.
The Yamaha XV1000 SE or Midnight Special is a special edition Yamaha V-twin cruiser motorcycle. The XV920 was made from 1983 to 1985 and was based on Yamaha's Virago line of V-twin cruisers that are part of Yamaha's XV generation first launched in 1981. The top speed of SV1000 SE is 172.0 km/h (106.9 mph) with a maximum acceleration is 0–100 km/h in 5.3 seconds.
