How to detect best used outboard motors?

The parameters of engine nameplate can not be checked only. Each engine has a fixed small nameplate. The nameplate can not be destroyed easily. Its technical parameters are marked on it: cylinder diameter, number of cylinders and fuel consumption (some of which are also marked on it), but we have to prove that the quality of the engine can not only depend on the surface.

Step 1: Engine appearance inspection before starting.

The new best used outboard motors looks very clean in unused condition. Let's see if there is oil and water on his fuselage, whether there is leakage or not, whether there is no grease on his exterior, especially in the dead corner which is not easy to see, it should be carefully observed. At the same time, we need to check all its circuit devices, whether the installation and fixing is done firmly, whether the cable joints are intact, and so on.

Step 2: Start listening.

When starting the engine, listen to his voice is not very smooth, very smooth. Good engines don't have noise. When the engine is in bad condition, you will hear some noise.

Step 3: Trial operation

Trial operation is mainly to test the transmission device to see if its response is sensitive. When pushing the throttle, the engine speed follows; when hanging in the forward gear, the boat will move immediately; then the combination of forward and backward gear box is very smooth; if all three requirements are met, the probability of engine failure is very small. But we can't say that the gearbox will go through this process from stationary to moving without noise. So, there is no problem with the slight gear meshing noise. If the noise is very strange or the vibration is abnormal, it means that the transmission system is wrong.

If the manufacturer doesn't want to show you what's inside the cabin, it may be a little tidy. So I would rather not buy it than suffer endless aftermath. Buy transparently, don't be fooled...
