BJTDLLX Short Shaft Outboard Motor
The BJTDLLX 12 HP two-stroke motor delivers 661–1763 pounds of thrust and speeds of 8–30 km/h. It includes water cooling and a CDI ignition system for reliable starts. The unit uses high-quality aluminum construction, which resists fracture and corrosion, making it suitable for small boats under 661 pounds, including inflatable, fiberglass, and wooden craft. It offers three forward/neutral/reverse gears for varied cruising.
Best for: Lightweight vessels that need simple, dependable propulsion without heavy installation work. Choose this if you want a compact, easy-to-mount engine with straightforward controls.
Caution: As a 12 HP two-stroke, you’ll need mixed fuel and regular maintenance to maximize life and fuel efficiency. Longer runs require monitoring for overheating in extreme conditions.
DUIBAII 2 Stroke 18 HP HangKai Outboard Motor
This 18 HP outboard offers up to 5500 rpm and a 8” three-blade propeller, delivering strong acceleration and solid top-end speed. The external fuel tank holds 6.34 gallons, supporting longer runs, while the carburetor design aims to improve fuel efficiency. The motor uses lightweight aluminum alloy construction and corrosion-resistant finishes for mixed water environments.
Best for: Boat owners who want an 18 HP engine with robust power, moderate fuel economy, and a capable setup for longer trips.
Caution: While fuel efficiency is improved, 18 HP still requires mindful operation to maintain performance; ensure the carburetor remains clean and the cooling system is not obstructed.
NAZEAOB 18 HP Outboard Motor
The NAZEAOB 18 HP outboard features a 2-stroke engine operating at 4,500–5,500 RPM and a maximum load capacity of about 2,204 pounds.

The kit provides a water pump repair solution compatible with Yamaha 60–90 HP two-stroke models across several years. It replaces the water pump components to restore cooling system performance. The kit emphasizes compatibility with common Yamaha models and offers a straightforward maintenance path for preventing overheating.
Best for: Yamaha outboard owners seeking a reliable pump repair kit to maintain engine cooling and prevent overheating during trips.
Caution: Confirm model compatibility and correct part numbers before installing to avoid fitment issues.
Buying Guide: Key Purchase Considerations
What boat size and weight will the engine handle? Match horsepower to the boat’s displacement and intended use. Smaller boats benefit from 6–18 HP motors for basic propulsion, while mid-range craft may require 50–90 HP for planing and better acceleration.
What mounting and shaft length are needed? Short shaft (for smaller transoms) vs. long shaft affects installation and prop clearance. Confirm the transom height and alignment with the chosen motor.
What about fuel and maintenance? Two-stroke engines tend to be lighter and simpler but require regular oil mixing and maintenance. Consider fuel tank capacity, efficiency, and fuel type when planning trips.
Will you need tilt/trim features? Tilt and trim aid handling at different speeds and load conditions. If so, verify compatibility with your engine and mounting hardware.
Maintenance readiness: Keep a compatible impeller kit handy to prevent overheating. Regular inspection of cooling, ignition, and fuel systems improves longevity.
FAQ
- What is a typical use case for a 12–18 HP outboard?
Best for small boats, inflatables, or lightweight fishing craft where easy handling and low weight are priorities.
- Do I need a tilt/trim mechanism for all boats?
No, but it improves handling on mid-range engines and helps with planing efficiency; check boat weight and propeller setup.
- Can I use maintenance kits from different brands?
Yes, but ensure compatibility with your specific Yamaha or other brand model and pump type; mismatches can cause cooling issues.
- What should I consider when choosing between 12 HP and 18 HP engines?
Assess boat size, desired speed, and fuel economy. Higher HP provides faster planing but increases weight and fuel use.
- Is it necessary to replace a water pump kit preemptively?
Yes, if the current pump shows signs of wear or you are operating in harsh water; a fresh kit restores cooling efficiency.
