A V-drive is a power transmission system for boats that consists (usually) of two gearboxes, two drive shafts, and a propeller. Whereas the conventional arrangement sites the engine with its gearbox aft, driving the propeller shaft directly, in a "V-drive" layout, the engine is reversed, to have the gearbox in front.
The difference between a saildrive and a Z-drive is that a saildrive's propeller shaft is fixed in place, pointing aft, whereas a Z-drive's propeller shaft can be rotated to any azimuth. Traditional sailboat transmissions consist of a simple horizontal output shaft extended rearward from the engine, through the stern via a stuffing box. The ...
The Z-drive is so named because of the appearance (in cross section) of the mechanical driveshaft or transmission configuration used to connect the mechanically supplied driving energy to the Z-drive azimuth thruster device. This form of power transmission is called a Z-drive because the rotary motion has to make two right angle turns, thus ...
Mechanical transmission, which connects a motor inside the ship to the outboard unit by gearing. The motor may be diesel or diesel-electric. Depending on the shaft arrangement, mechanical azimuth thrusters are divided into L-drive and Z-drive. An L-drive thruster has a vertical input shaft and a horizontal output shaft with one right-angle gear.
In 1959 Wynne left Kiekhaefer and in less than 90 days developed his own stern drive, which he subsequently patented. The first commercial introduction of sterndrives was the Volvo Penta "Aquamatic" at the 1959 New York Motor Boat Show. [1] [2] Kiekhaefer introduced a MerCruiser outdrive in 1961 at the Chicago Boat Show. By 1962, 16 ...
A power shuttle is an additional unit used in transmissions and is generally used in agricultural tractors.While the vehicle is moving forwards, the driver can pull a lever that makes it stop and go backwards at the same speed.
The diesel-electric transmission of power from the engine to the propeller affords flexibility in distribution of machinery within the vessel at a higher first cost than direct-drive propulsion. It is a preferred solution for vessels that employ pod-mounted propellers for precision positioning [ 21 ] or reducing general vibrations by highly ...
In this image, waves are created within the bow shock near the boat's initial interface with the water, and a rooster tail directly behind the boat. A rooster tail is a term used in fluid dynamics, automotive gear shifting, and meteorology. It is a region of commotion or turbulence within a fluid, caused by movement.
