Four-stroke outboards have been sold since the late 1920s, such as the Roness and Sharland. In 1962 Homelite introduced a four-stroke outboard a 55-horsepower (41 kW) motor, based on the four-cylinder Crosley automobile engine. This outboard was called the Bearcat and was later purchased by Fischer-Pierce, the makers of Boston Whaler, for use ...
1927 Johnson Seahorse outboard motor at the Tellus Science Museum. The original company that made Johnson inboard motors and outboard motors was the Johnson Brothers Motor Company of Terre Haute, Indiana, United States. They started building inboard 2-cycle marine engines in 1903 in a barn behind the house, along with matching boats.
4-Stroke Marine Diesel Engine System. Most modern larger merchant ships use either slow speed, two stroke, crosshead engines, or medium speed, four stroke, trunk engines. Some smaller vessels may use high speed diesel engines. The size of the different types of engines is an important factor in selecting what will be installed in a new ship.
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.
Another use of the V4 engine is in outboard motors for boats. The V4 configuration is popular for outboard marine applications due to its short engine length. In 1958, both Johnson and Evinrude introduced 70.7 cu in (1,159 cc) V4 outboards rated at 50 hp (37 kW) and weighing 200 lb (91 kg). [24]
