American outboard motors. The original trademark was (Xiyunlai), but later switched to "Zhuangsheng". The domestic Haima 65-horsepower 2-stroke machine was used by many people in eastern Guangdong in the early years. Now Haima seems not to be produced. 2 has been replaced. Now they are all 4-inch ones. If you buy an American model (Mercury), buy a Japanese Suzuki or Yamaha of similar quality.
