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 ...
Among the earliest representatives of the technology was the OMC Zephyr Saildrive, produced from 1977 to 1984. This was a two-stroke gasoline engine to which oil needed to be added on a 50:1 mixture. It was a derated version of the 32 cubic inch engine block used at that time on the OMC Evinrude 25/30/35 hp outboards.
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.
Placing the cooling radiator section in seawater rather than ambient air allows for the radiator to be smaller. The engine's cooling water may be used directly or indirectly for heating and cooling purposes of the ship. The Stirling engine has potential for surface-ship propulsion, as the engine's larger physical size is less of a concern.
Basic parts of an outboard motor. 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.
Jeep CJ; Jeep Wagoneer/Grand Wagoneer; Kaiser Jeep was purchased by AMC in 1970. The Buick 350 cu in (5.7 L) V8, AMC 232 I6, and AMC 327, 360 V8 engines in the FSJ Wagoneer and trucks used a 'nailhead' pattern TH400—also known as a "unipattern," as it was used by many other manufacturers (including Rolls-Royce and Jaguar) with an adapter ring—from 1965 to 1972.
The outdrive resembles the bottom half of an outboard motor and is composed of two sub-units: an upper containing a driveshaft connected through the transom to an engine which transmits power to a 90-degree-angle gearbox; and the lower containing a vertical driveshaft receiving power from the upper unit gearbox, transmitted through another 90 ...
A 16-horsepower (12 kW) inboard marine diesel engine, installed in a sailboat Engine room layout of a rescue boat An 11,100-horsepower (8,300 kW) 5-cylinder, 2-stroke, low-speed marine diesel engine, powering a ship. The first marine craft to utilize inboard motors were steam engines going back to 1805 and the Clermont and the Charlotte Dundas ...
