There are several well established, Japanese brands of outboard motors on US market, such as Honda, Mercury, Suzuki and Tohatsu. These are are all very good engines, with excellent characteristics, performance and durability. But, these are not cheap. In many cases cost of outboard motor one of these brands can be higher than cost of inflatable boat itself. 

However, there are also less expensive alternatives are now available, coming from China, such as Parsun, Hangkai, Hidea and few others. While there is some prejudice against outboard motors made in China, they are getting better and better over time. Most of these are in fact copies of Japanese outboard brands motors. When there is a choice between cost vs. perceived durability, and you are handy enough to open outboard top, and adjust it as needed, Chinese outboard motor might be a good and inexpensive option. 

In fact, most of issues with Chinese outboard motors comes from incorrect operations, not following proper procedures and using incorrect gasoline. For example, never run motor outside of water. Always use REC-90 Ethanol-free gasoline only. Always remove all gasoline from outboard if it not use for longer than few month. Ethanol easily clogs carburetor, and that is most common source of outboard engines troubles. While there are might be some minor issues with Chinese outboard motors, such as throttle handle label glued backward for example, when properly following break in procedures, using correct oil and gasoline, these engines can be great and inexpensive alternative to expensive Japanese brands. 

One of most popular Chinese brands at this moment seems to be Hangkai. They are sold on Amazon and Ebay and there are plenty of YouTube reviews videos of Hangkai outboard motors.

3. Please start the motor in the water. If the motor stops circulating water, please stop using it immediately and check the impeller of the water pump to see if the water outlet is blocked.
4. Please note that this product should use a mixture of two-stroke engine oil and 92 # unleaded gasoline. The running-in period of the new machine is 10 hours, during which the fuel ratio is 30L (7.93 gal) of gasoline to 1L (0.26 gal) of engine oil. After 10 hours, the ratio is 50 liters (13.21 gallons) of gasoline to 1 liter (0.26 gallons) of oil.

1. About the noise: All the gasoline machines are noisy, currently we did not test the decibel , but the noise is the same as the motorcycle, so it is a normal phenomenon

2. The machine itself is lightweight, it can use on boat weight of 100kg or less , load-bearing 4 people, but the speed is certainly not the same when one person on it or 4 people on it. Customer who has high expectations on speed, please be noted. Boat will not be as fast as JetSki.


One Year limited warranty applies to all new Hangkai outboard motors.
