Small 4-stroke outboard motors suit boaters who want compact gas-powered propulsion for fishing boats, dinghies, and inflatable watercraft. The 4HP ZLLIEZQU is best for buyers prioritizing a smaller engine and listed fuel details; the LIWBYYG and BJTDLLX 6.5HP models offer more power with water cooling. The two 6HP air-cooled options are alternatives for buyers comparing steering and operating features. Match horsepower, cooling type, mounting needs, and included equipment to your boat before choosing.
| Motor | Best suited for | Listed standout feature |
|---|---|---|
| ZLLIEZQU 4HP | Buyers seeking lower horsepower | 53.2CC engine and 1.2L tank |
| LIWBYYG 6.5HP | Buyers wanting water cooling | CDI ignition and reverse gear |
| BJTDLLX 6.5HP | Buyers wanting three gear positions | Forward, neutral, and reverse |
| HANGKAI 6HP | Buyers valuing flexible maneuvering | 360-degree steering |
| GrfceVue 6HP | Buyers seeking variable throttle control | TCI ignition and emergency shutoff rope |
ZLLIEZQU 4HP Air-Cooled Outboard Motor
This 4-stroke model has a 53.2CC, air-cooled single-cylinder engine and manual pull start. The listing specifies 4 horsepower, 1.5KW at 6,800 rpm, and claimed thrust of 350kg. Its stated fuel setup includes a 1.2L tank, 0.6L oil capacity, #90-or-higher gasoline, and listed consumption of 480g per hour.
Best for: Buyers who want a lower-horsepower option and value having engine and fuel-use specifications in the listing. It is described for small boats, fishing boats, and inflatable boats, including freshwater and saltwater use. Limitation: It is air-cooled, rather than water-cooled, and uses a manual pull start.
LIWBYYG 6.5HP Water-Cooled Motor
The LIWBYYG combines a 6.5HP four-stroke engine with CDI ignition and water cooling. It has a three-blade propeller, manual steering and tilt, and forward and reverse functions. The listing states a load capacity of 661 to 1,653 pounds and a mounting clip for a transom up to 1.57 inches thick. Its body is described as plastic and aluminum alloy.
Best for: Buyers seeking a 6.5HP motor with water cooling and reverse gear for an inflatable boat, kayak, or canoe. Limitation: The listing says the motor ships in two packages, so delivery may not arrive as one parcel. Check the stated transom limit against your boat.
BJTDLLX 6.5HP Motor With Fuel Tank
This 123CC, 6.5HP four-stroke motor is listed with water cooling and a fuel tank. Its three gear positions are forward, neutral, and reverse, and the throttle handle supports variable-speed control or constant-speed cruising. The listing also provides a gear-oil instruction: the gearbox is filled before leaving the factory, with subsequent checks suggested every ten hours of use.
Best for: Small-boat owners who want reverse and neutral as well as forward operation, and who prefer a listing that explains gear-oil checking. Limitation: The available product details do not specify tank capacity or transom dimensions, so verify those requirements before purchase.
HANGKAI 6HP Air-Cooled Outboard
This 6HP four-stroke motor uses an air-cooling system and a three-blade plastic propeller. The listed maneuvering features include 360-degree steering, a 180-degree turn for reversing, and manual lift and tilt for shallow-water use. The manufacturer describes its construction as plastic and aluminum alloy, with resistance to wear, rust, and corrosion.
Best for: Buyers who prioritize steering flexibility and manual tilt among the listed features. Limitation: The listing describes an air-cooled system, not water cooling. Check the boat’s mounting and operating requirements, which are not fully specified in the supplied product details.
GrfceVue 6HP Short-Shaft Motor
This 6HP four-stroke motor is identified as a short-shaft model and has air cooling and TCI ignition. The listing describes forward and neutral gears, throttle-based variable-speed control, an emergency flameout rope, and tilt adjustment pins. It also claims a speed range of 4 to 15 km/h at 4,500 to 5,500 rpm.
Best for: Buyers whose boat calls for a short shaft and who want the listed emergency shutoff and throttle-control features. Limitation: The described gear positions are forward and neutral; reverse is not listed. Confirm that this arrangement suits your maneuvering needs.
Buying Guide: How To Choose A Small 4-Stroke Outboard
How much horsepower does your boat need?
Compare the motor’s horsepower with the boat manufacturer’s capacity guidance and your intended load. The products here range from 4HP to 6.5HP. More horsepower is not automatically a better fit; boat size, passenger and gear load, and water conditions matter. The LIWBYYG lists a load-capacity range, but that figure should not replace the boat’s own rated limits.
Should you choose air cooling or water cooling?
These listings include both systems. The ZLLIEZQU, HANGKAI, and GrfceVue are air-cooled, while the LIWBYYG and BJTDLLX describe water cooling. Compare the stated cooling system and maintenance guidance for the specific model. Do not assume that all motors with similar horsepower have the same cooling design.
What should you check before ordering?
Confirm shaft length, transom thickness, mounting method, starting method, fuel requirements, and gear positions. The GrfceVue is identified as short-shaft, and the LIWBYYG specifies a transom limit. Other supplied listings leave some measurements or specifications unstated. Ask the seller or consult the complete product documentation when an essential fit detail is missing.
Which operating features matter most?
Reverse can help with maneuvering, while neutral and variable throttle affect how the motor is controlled. Compare these details directly: the BJTDLLX lists forward, neutral, and reverse; the GrfceVue lists forward and neutral. Also consider whether manual pull starting and manual tilt fit your routine.
Frequently Asked Questions
What is a small 4-stroke outboard motor used for?
It provides gas-powered propulsion for smaller craft such as fishing boats, dinghies, and inflatable boats. Check the engine’s specifications and your boat’s rated capacity to determine suitability.
Are these motors water-cooled?
Not all of them. The LIWBYYG and BJTDLLX listings specify water cooling; the ZLLIEZQU, HANGKAI, and GrfceVue listings specify air cooling.
Do all five motors have reverse gear?
No. The LIWBYYG and BJTDLLX list reverse. The GrfceVue lists forward and neutral only; reverse is not specified for the other models in the supplied details.
What fuel does the 4HP ZLLIEZQU use?
Its listing specifies #90-or-higher gasoline and states a 1.2L tank, 0.6L oil capacity, and fuel consumption of 480g per hour.
How can I confirm an outboard will fit my boat?
Check the boat’s transom requirements against the motor’s shaft length, mounting dimensions, and stated transom limit. If the listing does not provide those measurements, verify them with the seller before ordering.
