Detailed Specifications

Frequently Asked Questions

Is this 4HP outboard boat motor suitable for saltwater?

Yes. This engine is specifically designed for both saltwater and freshwater use. The materials and coatings offer enhanced resistance to corrosion, ensuring long-term durability even in marine environments.

How fast can it go?

Under typical conditions, this motor can achieve speeds between 10 and 16 nautical miles per hour, depending on the vessel’s load and water conditions.

Do I need to add water for cooling?

No. Thanks to its air-cooling system, this engine doesn’t rely on water intake for temperature control. That makes it ideal for fishing or boating in weedy, shallow, or debris-heavy waters where water-cooled engines can fail.

What kind of boat is it compatible with?

This 4HP motor is suitable for most small boats, inflatable dinghies, kayaks with a transom mount, aluminum fishing boats, and similar vessels. It fits boats with a transom plate height of approximately 17.3 inches.

Air Cooling = Less Maintenance, More Time on the Water ️

Unlike traditional water-cooled outboards, the integrated air-cooling system in this engine means you won’t have to worry about clogged water intakes, overheated motors, or pump failures. It simplifies upkeep and offers peace of mind for long days offshore or in remote locations where help isn’t nearby.

Easy to Handle, Built to Last ️

Weighing less than heavier outboards in its class, this engine is easy to mount, remove, and transport. The twist-grip throttle gives you smooth, controlled acceleration and responsive steering without requiring experience to master. Whether you’re trolling, exploring, or just cruising, it keeps your ride smooth and safe.

Maintenance Tips:

• Rinse with fresh water after saltwater use
• Use ethanol-free gasoline for best performance
• Inspect propeller and shaft regularly
• Change oil and check spark plug seasonally
