Safety information EMU33622 Outboard motor safety Observe these precautions at all times. EMU36501 Propeller People can be injured or killed if they come in contact with the propeller. The propeller can keep moving even when the motor is in neutral, and sharp edges of the propeller can cut even when stationary. ● Stop the engine when a person is in the water near you. ● Keep people out of reach of the propeller, even when the engine is off.
Safety information EMU33820 Gasoline exposure and spills Take care not to spill gasoline. If gasoline spills, wipe it up immediately with dry rags. Dispose of rags properly. If any gasoline spills onto your skin, immediately wash with soap and water. Change clothing if gasoline spills on it. If you swallow gasoline, inhale a lot of gasoline vapor, or get gasoline in your eyes, get immediate medical attention. Never siphon fuel by mouth.
Safety information dling and lead to an accident, capsizing or swamping. EMU33772 Avoid collisions Scan constantly for people, objects, and other boats. Be alert for conditions that limit your visibility or block your vision of others. ZMU06025 Operate defensively at safe speeds and keep a safe distance away from people, objects, and other boats. ● Do not follow directly behind other boats or waterskiers.

EMU33890 Boating safety publications Be informed about boating safety. Additional publications and information can be obtained from many boating organizations. EMU33590 Laws and regulations Know the marine laws and regulations where you will be boating- and obey them.
Safety information EMU33700 Steering and sailing rules and sound signals Whenever two vessels on the water meet one another, one vessel has the right-ofway; it is called the “stand-on” vessel. The vessel that does not have the right-of-way is called the “give-way” or “burdened”vessel. These rules determine which vessel has the right-of-way, and what each vessel should do. Stand-on vessel The vessel with the right-of-way has the duty to continue its course and speed, except to avoid an immediate collision.
Safety information EMU25531 Other special situations Crossing When two power driven vessels are crossing each other’s path close enough to run the risk of collision, the vessel which has the other on the starboard (right) side must keep out of the way of the other. If the other vessel is on your right, you must keep out of its way; you are the Give-Way vessel.
Safety information Reading buoys and other markers The waters of the United States are marked for safe navigation by the lateral system of buoyage. Simply put, buoys and markers have an arrangement of shapes, colors, numbers and lights to show which side of the buoy a boater should pass on when navigating in a particular direction. The markings on these buoys are oriented from the perspective of being entered from seaward (the boater is going towards the port).
