Features

  • High-quality Material: High-quality aluminum alloy has high hardness, corrosion resistance, and rust resistance, and is not easy to bend, so it can serve you for a long time. Many cooling holes and water cooling systems provide excellent heat dissipation to prevent the engine from burning out after a long time of use.
  • Excellent Load-bearing Capacity: With solid aluminum alloy material and a powerful engine, the outboard engine has a maximum load of 2204 pounds to meet different needs. (The heavier the load, the slower the speed).
  • Excellent Endurance: Low fuel consumption, efficient two-stroke motor, and large capacity fuel tank (6.34 gallons) provide you with a long endurance to meet the needs of short/long distance travel. 2-stroke 18hp engine (4500 to 5500rpm) provides strong power for you to drive fast and save a lot of time and energy.
  • Flexible Steering: Forward, neutral and reverse gears, and a 360-degree steering function allow you to flexibly control the direction of the ship. Stepless speed change and constant speed cruise function make it easy for you to adjust the running speed and stable navigation at a constant speed to bring you a more comfortable user experience.
  • Easy to Operate: The manual start function allows you to operate easily by pulling the start rope and opening the speed switch on the handle. Its long non-slip handle(20 inches in length) is easy to grasp. The red stop button allows you to stop the engine by pressing it for a few seconds.

Description

LyeXD outboard motor is well-made, fast & powerful, easy to operate and fuel-efficient. Come and buy it! LyeXD is a brand that specializes in manufacturing high-quality products. Our outboard motors undergo rigorous quality control and testing at the factory to ensure durability and superior performance. Our goal is to ensure your outboard motor always runs efficiently and reliably. Whether you are an outboard enthusiast or a service center, LyeXD is committed to providing comprehensive assistance. The outboard engine is ideal for inflatable boats, fishing boats, sailboats and small yachts. Gear Oil Filling Method: There is a screw on the gearbox, unscrew the screw to add gear oil. Gear oil is not filled before each machine leaves the factory, so please fill gear oil when using for the first time. After that, add according to personal use, and check every ten hours. Notes: 1. The two-stroke outboard must use a mixture of No. 92 gasoline and two-stroke engine oil. 2. The volume ratio of gasoline and oil during the running-in period of the new machine is 25:1. 3. After the running-in period, the volume ratio of gasoline and oil is 50:1. 4. Special attention: gasoline and engine oil must be pre-mixed and stirred evenly, and then poured into the fuel tank. 5. The outboard motor must be started in water, do not start the engine on shore. 6. Loosen the vent screw on the fuel tank cover counterclockwise when starting. 7. When the outboard motor is started, the emergency flameout rope should be inserted, and the other end should be placed on the wrist or belt. 8. The running-in period is about 10 hours or a month, and during the running-in period, do not drive with a high accelerator. 9. Replace the gear oil after the running-in period, and the second replacement time is after 100 hours or about six months. Model: 18HP Horsepower Long Axis Displacement: 246CC Gear Ratio: 2.08 (27:13) Number of Cylinders: 2 Speed: 4500-5500RPM Gear: F-N-R Recommended Engine Oil: 2 Stroke Engine Oil Mixing Ratio: Fuel: Oil = 50:1 Refueling Method: 92 Unleaded Gasoline is Recommende Low fuel consumption, efficient two-stroke motor, and large capacity fuel tank (6.34 gallons) provide you with a long endurance to meet the needs of short/long distance travel. Forward, neutral and reverse gears, and a 360-degree steering function allow you to flexibly control the direction of the ship. 2-stroke 18hp engine (4500 to 5500rpm) provides strong power for you to drive fast and save a lot of time and energy. The three-blades propeller with a streamlined design provides you with greater power. The silencer cover can absorb the noise generated by the fan through the internal sound-absorbing material, thus providing a quieter working environment. Many cooling holes and water cooling systems provide excellent heat dissipation to prevent the engine from burning out after a long time of use. Stepless speed change and constant speed cruise function make it easy for you to adjust the running speed and stable navigation at a constant speed to bring you a more comfortable user experience.

  • Cheep
Not a lot of speed but it starts and runs. At this price I can buy another one for the same price it used to take to tune up my old Honda. This thing is noisy. The exhaust is in a bad place. Burnt the stew out of my arm.

  • It's a cheap boat motor
I definitely expected issues because it's a cheap Chinese motor. Couldn't get it to stay running from out of the box. Contacted the company and they said needing to tune the carburetor. Tuning the carburetor didn't do anything if anything it made it worse. The company then sent me a new carburetor to install. Installed a new carburetor and realized it wasn't the exact one but made it work with parts from the old one. It starts and runs and still not the best and the throttle could be better. ... show more

  • motor
i recently purchased the 3.5 HP outboard motor for my small fishing boat and I'm impressed with its performance. This motor is lightweight, easy to start, and provides sufficient power for my needs. It's perfect for navigating through calm waters and has a decent throttle response. The motor is also relatively fuel-efficient, which is a big plus for me. I've used it for 2 hours on a single tank of gas and still had some left over. One thing to note is that this motor may not be suitable for larger boats or rough waters Overall, I'm happy with my purchase and would recommend this motor to anyone looking for a reliable and affordable outboard for small-scale boating ... show more

  • La velocidad y mal empaquetado, mojado del mismo aceite del motor La velocidad y mal empaquetado, mojado del mismo aceite del motor
Cuando lo recibí, el motor estaba mojado de aceite incluso entró en el escape cuando lo prendí el motor tiró mucho humo blanco como que si explotara y tube que limpiarlo y secarlo y ademas En el manual no decía que aceite debería de llevar en la transmisión Pero yo puse -Del motor 10w30 movil -Y del transmisión no tenia en especial cual es el adecuado pero si le di liquido de transmisión manual de carro - de gasolina pura es mejor la 92 Y decía que andaría a velocidad como de 55mph Pero la realidad solo va como 10 mph con una sola persona. Ahora si se sube 4 personas solo va como a 3 o 4 mph espero. Pues si es un buen motor pero mas lo menos por eso le doy solo 3 de 5. Al parecer la que corre mas son las de 8 o 12 hp Esta es solo de 4hp Que vale 240 y algo mas envió saldrán en 340 ... show more

  • Run Away!!
Don’t waste your money. Got mine put it on the boat. Filled oil up and took for a spin. Done great. Went out about a month later engine locked up tighter than Fort Knox. Didn’t overheat or anything, had perfect amount of oil.

  • Works - but needs some preparation
1. Prop is held on by a split pin. May wish to replace with quality bolt and nut. 2. Choke on and off labelling is switched (I fixed with a tape label) 3. Ships with no gear oil in final drive - make sure to add! Sorry, I could not show it running - Amazon only allows one video. Will post an updated review once it’s on the boat ... show more
