Engine mount bolt
A fully thread bolt coated with a sealing agent has been used for mounting the engine.
This gives a sealing function to the bolt, which will prevent the bolt from sticking by saltwater enter-
ing into the bolt hole for crystallizing and corroding.
Therefore, the bolts can be removed easily, which obtained better servicing.
NOTE:
If the bolt is reused, apply LOCTITE 572 to the bolt threads.
