DUIBAII 2 Stroke 18 HP HangKai Outboard Motor
The DUIBAII HangKai 18 HP outboard combines lightweight aluminum construction with a rugged finish designed for both freshwater and saltwater use. It features a 2-stroke engine with a maximum output of 13.2 kW (18 hp) and a top speed near 5500 rpm, paired with an 8″ three-blade propeller to optimize water thrust. A sizable external fuel tank (about 6.34 gallons) supports longer runs, while an efficient carburetor helps curb fuel consumption to around 1.18 gal/h. Best for boats that demand strong punch, especially wooden or small-rib boats where stability matters. Better for open water and faster transit than smaller 4-6 hp units. A consideration: 2-stroke engines typically require mixed fuel and regular maintenance to sustain peak performance.
NAZEAOB 2 Stroke 18HP Outboard Motor
The NAZEAOB 18HP outboard uses durable aluminium alloy and a CDI ignition system with water cooling for reliable performance. It delivers 18 hp within a 4,500-5,500 rpm operating window and supports a maximum load around 2,204 pounds, making it suitable for moderately larger inflatables or small cabins. This model aims at fast transit and steady handling with a robust build that resists corrosion. Choose this if you need strong mid-range power with predictable load capacity and simple gear control. Limitation: heavier loads may reduce top speed.
BJTDLLX Short Shaft Outboard Motor 12 HP
This 12 HP 2-stroke outboard uses aluminum construction for durability and a water cooling system to extend service life. Its short shaft makes it well-suited for smaller boats under 21 feet, including wooden and inflatable craft. The engine provides 5500 rpm on top and 661-1763 pounds of thrust, with forward, neutral, and reverse gears for versatile maneuvering. Best for cost-conscious buyers needing reliable power on compact boats. A potential drawback is that 12 hp is a step down from 18 hp options, which may affect speed and load tolerance in heavier setups.
CUKUSIN 4 Stroke Outboard Motor 4 HP
The CUKUSIN 4 HP outboard is a compact option designed for small inflatable boats, kayaks, canoes, and dinghies. It uses a four-stroke engine with air cooling, offering safer operation and easier maintenance. Weighing roughly 15 kg, it’s easy to handle and supports round-the-clock online assistance. Best for budget-minded buyers or as a backup motor for emergency use. Limitation: only 4 hp means slower speeds on larger loads or bigger boats.
Buying Guide
What to consider when choosing a 45 hp range motor
Power needs: If you frequently carry heavier loads or travel longer distances, two 18 hp motors may be preferable for redundancy and performance. For smaller craft, 12 hp or 9 hp engines can be more economical and easier to haul.
Fuel type, efficiency, and runtime
Gasoline 2-stroke engines provide high power-to-weight but require oil mixing and more maintenance. Four-stroke engines tend to be cleaner, quieter, and more fuel-efficient but can be heavier. Consider the fuel tank size and consumption as a proxy for runtime between refuels.
Durability and construction
Aluminum alloys offer corrosion resistance and lighter weight, which improves buoyancy and handling. Water cooling systems help maintain engine temperature in extended runs and saltwater environments.
Mounting and compatibility
Short shaft versus long shaft affects mounting height and stern clearance. Check your boat’s transom height and ensure proper gearcase depth for optimal propulsion and steering control.
Maintenance and support
Look for engines with accessible parts, CDI ignition reliability, and available service networks. Consider warranty terms and the availability of spare parts in your region.

FAQ
- Q: Which motor is best for a wooden boat? A: The DUIBAII 18 HP and NAZEAOB 18HP both offer solid aluminum builds suitable for wooden boats.
- Q: Is a 4-stroke motor better than a 2-stroke? A: Four-stroke engines are typically quieter and more fuel-efficient, but 2-stroke engines provide higher power-to-weight ratios.
- Q: Do I need a long or short shaft? A: Short shafts fit smaller transoms; long shafts suit taller transoms or deeper hulls to prevent cavitation.
- Q: Can these motors be used in saltwater? A: Several models claim saltwater compatibility with proper maintenance and rinse after use.
- Q: What maintenance is required? A: Regular oil and fuel system checks, cooling system maintenance, and propeller inspection are standard across models.
- Q: Are electric trolling motors comparable to gas engines in power? A: Trolling motors provide precise control and quiet operation for fishing, while gas engines deliver higher propulsive power for speed and load.
