Air cooled outboard motors are a type of outboard that rely on air circulation directly to eliminate engine heat. They typically use a system of cooling fins and deflector plates.

Simply put, the air cooled outboard is cooled as air passes over. In comparison, the water cooled outboard uses (raw/natural or fresh) water to absorb heat from the engine.

As you can imagine, air cooling systems don't require as much power and are not as effective as water-cooled systems. Therefore, the air cooled outboard motors are better suited for small horse-powered outboard engines.

Outboard motor cooling systems work similarly to your cars or motorcycles. As mentioned, the air cooled outboards use a fan to draw air over the hot areas (the engine and exhaust manifold) to dissipate engine heat.

In comparison, with water-cooled outboards, the lake or sea water is pumped through the engine block and then ejected to achieve the cooling effect.
