## Features

- 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.
- 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 whenone person on it or 4 people on it . Customer who has high expectations on speed, please be noticed.
- It can be marched with inflatable boats, rubber boats or fishing boats.
- Necessary: you have to prepare a boat-motor stand or Hanging board on your boat.
- Two strokes 4 hp are controlled by the handle, which is operated by the clutch. There is no Neutral, only idle mode or low speed mode
