1979 Evinrude 70 HP outboard, cowling and air cleaner removed, exposing its shift/throttle/spark advance linkages, flywheel, and three carburetors. Ole Evinrude was born in Gjøvik, Norway on April 19, 1877; five years later, his family emigrated to the United States, settling near Cambridge, Wisconsin. Interested in mechanics from an early age ...
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.
By 1921, Evinrude was back in business, in a venture he called the ELTO Outboard Motor Company. His new offering was the Evinrude Light Twin Outboard, a motor partly made of aluminum, reducing its weight by a third. Popular with the fishing fleets, this revolutionary engine outstripped sales of Evinrude's original outboard motor within three years.
Break-in or breaking in, also known as run-in or running in, is the procedure of conditioning a new piece of equipment by giving it an initial period of running, usually under light load, but sometimes under heavy load or normal load. It is generally a process of moving parts wearing against each other to produce the last small bit of size and ...
Problems of fuel boiling and vapor lock can occur in carbureted engines, especially in hotter climates. Since the float chamber is located close to the engine, heat from the engine (including for several hours after the engine is shut off) can cause the fuel to heat up to the point of vaporization.

Such was the quality of the metals used, that many are still operational many decades later. Ultimately, the Seagull product could not match more modern outboards such as Yamaha, Evinrude and Tohatsu, which were more efficient (with fewer emissions), more attractive, and more user-friendly. British Seagull ceased production of complete engines ...
Typically in smaller (less than 10 hp or 7.5 kW) and older engines, a narrow shear pin through the drive shaft and propeller hub transmits the power of the engine at normal loads. The pin is designed to shear when the propeller is put under a load that could damage the engine.
