Brief Introduction to Outboard Motors

The small four-stroke air-cooled outboard motor is a lightweight and high-efficiency marine propulsion device specially designed for small vessels (such as plastic boats, wooden boats and fiberglass fishing boats). It adopts a four-stroke cycle engine (intake, compression, combustion, exhaust) combined with an air-cooled heat dissipation system, eliminating the need for water-cooling devices, and features a compact structure and easy installation.

Its working principle is based on power generated by fuel combustion: the piston completes four strokes inside the cylinder, and the ignited fuel mixture pushes the crankshaft to rotate, which in turn drives the propeller to propel the vessel. The air-cooled system achieves natural cooling through the heat sinks on the engine casing and airflow from the fan, avoiding the complex pipelines and water pumps of water-cooled systems, thus enabling simple maintenance and low risk of clogging.

The main advantages are as follows:

High Efficiency and Environmental Friendliness: The four-stroke design ensures high fuel utilization rate, saving 20–30% of fuel consumption compared with two-stroke models, and greatly reducing exhaust emissions, which is in line with the trend of green navigation.

Durable and Low-Maintenance: The air-cooled structure has no liquid cooling components, reducing the overall weight (the whole machine usually weighs 20–50 kg) and the risk of corrosion, making it suitable for long-term use in both freshwater and seawater environments.

Cost-Effective and Practical: It features low purchase cost and easy starting, making it ideal for individual users and small vessels.
