Description
Technical Field
[0001] This utility model relates to the field of outboard motor starting technology, specifically to a one-button start system for an outboard motor with a supercapacitor. Background Technology
[0002] Outboard motors, as the name suggests, are propulsion engines installed on the outside of the hull (side of the boat). They are usually suspended on the outside of the stern plate and are also called outboard engines. Outboard motors are highly integrated and easy to install and purchase, making them the preferred power source for personal recreational boats, and they are also widely used in commercial operations.
[0003] Problems with traditional outboard motor starting methods:
[0004] Currently, most outboard motors use traditional battery starting methods. Traditional batteries have some limitations; for example, their performance degrades significantly in low-temperature environments, leading to starting difficulties.
[0005] Batteries have a long charging time, and their ability to store electricity gradually decreases with use, requiring regular replacement and increasing operating costs.
[0006] The requirement for a one-click start function:
[0007] With the development of ship technology, the requirements for the ease of operation of outboard motors are getting higher and higher. One-button start function has become one of the functions expected by outboard motor users, but traditional batteries are insufficient in achieving efficient one-button start. Utility Model Content

At this time, the starter motor 5 operates, and the starter motor 5 drives the flywheel to rotate, thereby starting the machine and achieving the effect of starting the outboard motor with one button.
[0052] Advantages of Supercapacitor 1:
