The pivoting design allows the outboard motor to be swiveled by the operator in almost all directions: Sideways for direction, up and down to change the thrust line according to speed or bow lift, elevate completely out of water for easy starting, placing the drive shaft and the propeller forward along the side of the boat for reverse, or put ...
Modular propellers may be fitted to aircraft as well as boats. [1] The benefits of a modular propeller are that its specifications (such as blade pitch or propeller diameter) may be altered to suit varying conditions; and it becomes much easier to replace damaged elements, such as a broken blade. Traditional one-piece propellers may be ...

Folding propellers reduce drag while not in use, thereby allowing for more speed or reduced fuel consumption. Folding propellers are no more efficient than fixed blade propellers, and have much poorer performance in astern. Less noise and vibration than fixed blades when not in use, since fluid flow will not cause the propeller to rotate.
The Yamaha FS1-E has a 49 cc (3.0 cu in), single cylinder, two-stroke, air-cooled, rotary disc-valved engine with a four-speed gearbox. The FS1-E was the FS1 with the suffix E, which stood for England (differing from the models sold in other countries as the FS1-E had more cycle parts in common with other UK-imported Yamaha models).
A ducted propeller, also known as a Kort nozzle, is a marine propeller fitted with a non-rotating nozzle. It is used to improve the efficiency of the propeller and is especially used on heavily loaded propellers or propellers with limited diameter. It was developed first by Luigi Stipa (1931) and later by Ludwig Kort (1934). The Kort nozzle is ...
In marine propulsion, a variable-pitch propeller is a type of propeller with blades that can be rotated around their long axis to change the blade pitch. Reversible propellers—those where the pitch can be set to negative values—can also create reverse thrust for braking or going backwards without the need to change the direction of shaft revolution.
In 1912, Humber produced a light car called the Humberette with a Humber-made V-twin side-valve engine of 998cc. The engine had a directly attached clutch, 3-speed gearbox and prop shaft output to a rear differential. A water cooled version of this engine was made available in 1914, but WW1 ended Humberette production in 1915. [25]
