#Mercury 50 hp 2 stroke service manual manual

Mis- matched or incorrect fasteners can result in damage or malfunction, or possibly personal injury. Ameri- can bolts use radial lines for this purpose, while most American nuts do not have strength markings. Numbers on the heads of the metric bolts and on the surface s of metric nuts indicate their strength. It is important to note, during any maintenance proce- dure replacement fasteners must have the same measurements and strength as those removed. Any time the intake or exhaust openings are exposed during service they should be covered to protect against accidental entrance of foreign material which could enter the cylinders and cause extensive inter- nal damage when the engine is started. When performing any work where electrical terminals could possibly be grounded or touched by the mechanic, the battery cables should be disconnected at the battery. It should be kept in mind, while working on the prod- uct, that the electrical system and ignition system are capable of violent and damaging short circuits or se- vere electrical shocks.
