The submarine could also run its diesel using a snorkel. The Quebec had three drive shafts: a 32D 900 bhp (670 kW) diesel on the centre shaft and two M-50P 700 bhp (520 kW) diesels on the outer shafts. In addition a 100 hp (75 kW) "creep" motor was coupled to the centre shaft. The boat could be run at slow speed using the centreline diesel only.
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 ...
While paddles and sails are still used on some smaller boats, most modern ships are propelled by mechanical systems consisting of an electric motor or internal combustion engine driving a propeller, or less frequently, in pump-jets, an impeller. Marine engineering is the discipline concerned with the engineering design process of marine ...
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.
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 ...
Boat building is the design and construction of boats (instead of the larger ships) — and their on-board systems. This includes at minimum the construction of a hull , with any necessary propulsion, mechanical, navigation, safety and other service systems as the craft requires.
The Voith Schneider propeller was originally a design for a hydro-electric turbine. [2] Its Austrian inventor, Ernst Schneider, had a chance meeting on a train with a manager at Voith's subsidiary St. Pölten works; this led to the turbine being investigated by Voith's engineers, who discovered that although it was no more efficient than other water turbines, Schneider's design worked well as ...
A home-made pop pop boat using a coil type boiler Pop pop boat with accessories. (Melted candle in the pan with a lit piece of wick provides the heat source.) A pop pop boat is powered by a simple heat engine. This engine, sometimes referred to as a pulsating water engine, [1] consists of a boiler and one or more exhaust tubes. A heating ...
