Introduction to Small Four-Stroke Air-Cooled Outboard Motors

Small four-stroke air-cooled outboard motors are lightweight, high-efficiency marine propulsion devices designed specifically for small boats (such as plastic boats, wooden boats, and fiberglass fishing boats). They adopt four-stroke cycle engines (intake, compression, combustion, exhaust) combined with an air-cooling system, eliminating the need for water-cooling devices, resulting in a compact structure that is easy to install.

The working principle is based on generating power through fuel combustion: the piston completes four strokes in the cylinder, and the ignited fuel mixture pushes the crankshaft to rotate, driving the propeller to propel the boat. The air-cooling system achieves natural cooling through the heat sinks on the engine casing and the airflow from the fan, avoiding the complex pipelines and water pumps of water-cooling systems, thus ensuring simple maintenance and low susceptibility to blockages.

The main advantages include:

High efficiency and environmental friendliness: The four-stroke design achieves high fuel utilization, saving 20-30% of fuel consumption compared to two-stroke models, while significantly reducing exhaust emissions, in line with the trend of green navigation.
Durability and low maintenance: The air-cooled structure has no liquid cooling components, reducing weight (the whole machine usually weighs 20-50 kilograms) and lowering the risk of corrosion, making it suitable for long-term use in freshwater or seawater environments.
Economic and practical: It has a low purchase cost and is easy to start, making it suitable for individual users and small boats.
