COFECO Outboard Motor, 6.5 HP

COFECO’s 6.5 HP four-stroke outboard delivers a compact 123cc engine with a water-cooling system and CDI ignition. It’s designed for small boats and aquaculture needs where fuel efficiency and reliable ignition matter. The engine achieves a maximum output around 4.8 kW, and a manual start keeps maintenance simple for remote locations. Its low fuel consumption—about 0.52 gal/hour—helps reduce operating costs while providing steady performance for calm lakes or sheltered rivers.
Key features
- 4-stroke, 6.5 HP with 123cc displacement
- Water cooling and CDI ignition
- Manual start
- Economical fuel use
COFECO Hangkai 12HP Outboard Motor

This COFECO model targets higher thrust with a 12 HP output in a compact 169cc two-stroke design. Note: This is a two-stroke engine and not a four-stroke option. It features a CDI ignition system and a water-cooling layout to sustain performance under load. With a 5500 RPM range, it offers substantial thrust (approximately 661-1763 lbs) for faster planing and cruising in larger inflatables or small sailboats.
Notable points
- 2-stroke 12 HP engine
- Water cooling with CDI ignition
- Three-speed gear system for flexible cruising
Cbhfmljd 4-Stroke 9HP Outboard Motor

With a 225cc displacement and a 9 HP four-stroke design, this model emphasizes stable performance and water cooling for reliable operation on inflatable boats or small yachts. It lists a 4-stroke engine architecture, compression ratio around 8.4:1, and a user-friendly starting method with transistor ignition. The unit includes gear transmission with forward-neutral and a clutched start feature to prevent prop rotation when idling, contributing to safe handling in crowded waterways.
Key elements
- 4-stroke, 9 HP, 225cc
- Water cooling and TCI ignition
- Forward and neutral gears (no reverse)
- Start-in-gear protection
BJTDLLX 6.5HP Outboard Motor

This BJTDLLX model provides a compact 123cc, 6.5 HP four-stroke option with a water-cooling system. It emphasizes easy carrying, a larger fuel tank capacity, and three-gear cruising for adjustable speed. The gear oil filling method is straightforward, with pre-filled oil at the factory and simple maintenance steps thereafter. The combination of light weight and reliable cooling makes it a practical choice for inflatable and small rigid-hulled boats.
Highlights
- 4-stroke, 6.5 HP, 123cc
- Water cooling and CDI ignition
- Three-gear cruising
- User-friendly maintenance
LIWBYYG 12HP 2-Stroke Outboard Motor

LIWBYYG presents a robust 12 HP two-stroke option with 169cc displacement and water cooling. While it is not a four-stroke device, it features CDI ignition and a broad thrust range that supports 8-30 km/h speeds. The engine is designed for rugged use, including rubber boats and inflatable craft, with efficient fuel use and a sizable external fuel tank to extend operation between refuels.
Considerations
- 2-stroke, 12 HP, 169cc
- Water cooling and CDI ignition
- Three-gear drive with forward/neutral/reverse
- Higher power density, more maintenance on 2-stroke systems
Buying Guide: Key Purchase Considerations
Power needs, vessel size, and operating conditions drive selection among outboard motors. Here are essential factors to weigh when choosing a 10 HP class outboard or its closest equivalents in four-stroke designs:
- Engine type: Four-stroke vs. two-stroke. Four-stroke motors generally offer smoother operation, broader fuel efficiency, and lower emissions, while two-stroke engines can deliver higher power-to-weight ratios and easier maintenance in some contexts. For this list, four-stroke options emphasize efficiency and reliability for calm or coastal use.
- Displacement and power curve: Match engine displacement and horsepower to the boat size, load, and desired speed. For smaller craft, 6.5–9 HP four-stroke units are typically suitable; larger inflatables may benefit from higher power but require heavier equipment handling.
- Cooling system: Water-cooled engines maintain temperature under load and are common for salt and freshwater use. Air-cooled units can be lighter but may require careful heat management in hot conditions.
- Ignition system: CDI and TCI CDI ignitions provide reliable starts and smoother operation in variable weather conditions. Look for engines with simple manual start mechanisms if you frequently operate in remote areas.
- Gear options and cruise control: Three-speed gears (forward/neutral/reverse) and continuous cruise features offer flexible pacing and stable cruising for different water conditions and loads.
- Maintenance and parts availability: Choose brands with readily accessible spare parts, gear oil, and service networks. User-friendly maintenance steps (like visible oil checks and simple gear oil filling) extend engine life.
- Weight and mounting compatibility: Check shaft length (short vs. long) and mounting patterns to ensure compatibility with your boat transom height and overall balance.
- Fuel economy and operating costs: Four-stroke engines typically provide better fuel efficiency and longer life with lower emissions. Expect variations based on RPM, load, and propeller selection.
When evaluating options, consider your typical boating scenarios: fishing in calm lakes, short-range river trips, or small coastal ventures. A lighter, fuel-efficient four-stroke with CDI ignition can offer dependable starts and predictable performance for routine outings, while keeping long-term maintenance manageable.
