All the lower parts of the boat should be properly lubricated to have smooth running and to avoid the damage of the parts too. As the reservoir should not contain any fluid like water and so on , so it is better to have a check the drive then and there to ensure whether there is any water content is present or not which is very simple and worth too. The electronic control module is used in all the engines to control the mechanism using the digital tools and it is very much useful to identify the problems also very easily and promptly too. The metal attachment will be found at the bottom of the boat which is called as the anodes and as with the usage of the salt water it may get decayed and it should be replaced with the correct time interval to protect the boat from the unnecessary and expensive repair.
