BJTDLLX Short Shaft Outboard Motor, 12 HP

The 2-stroke 12 HP outboard delivers 661-1763 pounds of thrust and speeds of 8-30 kilometers per hour. It uses water cooling to maintain performance and has a vent design that extends service life. Best for mid-sized inflatables, small fiberglass boats, and wooden craft that require reliable thrust in a compact package.
Best for: anglers or light-boat owners who want strong, steady power with simple maintenance. Better for boats under roughly 661 pounds and under 19.69 feet.
Limitation: The 2-stroke design requires fuel mixing and more routine maintenance than some 4-stroke options.
YIYIBYUS 2.3HP 52cc Outboard Motor

This 52cc, 2-stroke motor provides 1.7 kW / 2.3 HP, with an idle speed around 2800-3200 rpm and operating range up to 8500 rpm. Made from aluminum and PP, it emphasizes durability and corrosion resistance in both freshwater and saltwater environments. Best for tiny dinghies, inflatable boats, and kayaks needing light, fuel-efficient propulsion.
Best for: ultra-light, portable setups and occasional short trips where weight savings matter. Choose this if you prioritize portability over high-speed thrust.
Limitation: Lower power output means slower acceleration on heavier or larger small crafts.
BJTDLLX 6HP Outboard Motor

This 2-stroke 6 HP engine offers a robust balance of power and control. It features a 360° steering rotation, enabling easy reverse and directional maneuvering. The aluminum construction provides corrosion resistance, and the model supports small watercraft like fishing boats and dinghies. Best for: boaters who want reliable mid-range power with flexible steering. Limitations: may require more maintenance than some electric or newer lightweight models.
PERFERATE 6HP 2 Stroke Outboard

Rated at 6 HP with a 102cc displacement, this model uses water cooling and a CDI system with tiller control. It reaches up to 5500 rpm, delivering fast acceleration for inflatable boats and dinghies. Best for: budget-conscious buyers seeking a solid power-to-weight ratio with straightforward throttle control. Limitation: lower power than multi-horsepower units, not ideal for larger or heavier small boats.
DUIBAII 18 HP HangKai Outboard

This 2-stroke 18 HP engine delivers up to 5500 rpm, with aluminum construction and a water cooling system for reliability in varied conditions. The external fuel tank capacity supports longer runs, and the 8″ three-blade propeller provides efficient thrust. Best for: boats needing a stronger pull, such as larger inflatables or small powerboats. Limitation: higher power comes with more weight and potentially higher fuel consumption.
Gosangom 3.5HP 2-Stroke Outboard

This 3.5 HP, 2-stroke motor weighs about 21.6 lbs and uses a lightweight aluminum alloy with corrosion resistance. It features a 6.7″ three-blade propeller and a fuel-efficient carburetor, offering a practical balance of portability and performance. Best for: very small boats that require dependable, light propulsion. Limitation: modest power compared with higher HP options.
Buying Guide
What should I consider when choosing a small outboard motor?
- Boat size and weight: Heavier boats require more power; ensure the motor’s thrust aligns with your boat’s displacement (weight plus passengers and gear).
- Power vs. weight: Higher HP delivers faster speeds but adds weight and fuel use. Match your typical outing length and speed needs.
- Stroke type: Two-stroke motors are lighter and often cheaper but require fuel mixing and more maintenance; four-stroke options tend to be quieter and cleaner but heavier.
- Cooling method: Water-cooled engines handle heat better and perform longer in hot conditions; consider saltwater resistance if you boat in brackish or marine environments.
- Fuel system and tank capacity: Larger tanks extend run time but increase weight. Some models allow external tanks for longer trips.
- Ease of installation: Short vs. long shaft length affects compatibility with your transom height. Look for simple mounting and lightweight designs if you plan frequent swaps.
- Maintenance needs: Aluminum construction resists corrosion, but regular cleaning and fuel system care help longevity.
- Controls and steering: Models with 360° steering or easy reverse can simplify maneuvering in tight spaces.

FAQ
- Q: Do these motors require fuel mixing?
- A: Many listed are 2-stroke engines and require fuel-oil mixing as specified by the manufacturer.
- Q: Are electric options included?
- A: This guide focuses on gasoline-powered and one electric model; consider electric if you need quiet, emission-free propulsion for small boats.
- Q: What shaft length should I choose?
- A: Short shaft models fit shallow transoms; confirm your boat’s transom height before buying.
- Q: Is maintenance costly?
- A: Maintenance varies by model, but aluminum construction and water cooling generally improve durability and reduce corrosion-related issues.
- Q: Can I install these myself?
- A: Most listed models are designed for straightforward installation, but confirm compatibility with your boat’s transom and mounting hardware.
- Q: Which motor is best for inflatable boats?
- A: Lighter, compact models with adequate thrust, such as 3.5–6 HP options, are often ideal for inflatable crafts.
