General information is a good idea to wear a PFD whenever boating. At a minimum, children and non- swimmers should always wear PFDs, and everyone should wear PFDs when there are potentially hazardous boating condi- tions. Gasoline is highly flammable, and its va- pors are flammable and explosive.

General information Yamaha outboard motors are fitted with pro- pellers chosen to perform well over a range of applications, but there may be uses where a propeller with a different pitch would be more appropriate. For a greater operating load, a smaller-pitch propeller is more suit- able as it enables the correct engine speed to be maintained.
For instructions on propeller removal and in- stallation, see page 51. EMU25760 Start-in-gear protection Yamaha outboard motors affixed with the pictured label or Yamaha-approved remote control units are equipped with start-in-gear protection device(s). This feature permits the engine to be started only when it is in neutral.
