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.
U6BV37E0.book Page 2 Wednesday, May 1, 2013 8:56 AM Safety information EMU33780 Modifications Do not attempt to modify this outboard motor. Modifications to your outboard motor may reduce safety and reliability, and render the outboard unsafe or illegal to use. EMU33740 Boating safety This section includes a few of the many important safety precautions that you should follow when boating. EMU33710 Alcohol and drugs Never operate after drinking alcohol or taking drugs.
U6BV37E0.book Page 3 Wednesday, May 1, 2013 8:56 AM Safety information ● ● ● Avoid areas with submerged objects or shallow water. Ride within your limits and avoid aggressive maneuvers to reduce the risk of loss of control, ejection, and collision. Take early action to avoid collisions. Remember, boats do not have brakes, and stopping the engine or reducing throttle can reduce the ability to steer.

U6BV37E0.book Page 5 Wednesday, May 1, 2013 8:56 AM Safety information 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. When you maintain your direction and speed, the other vessel will be able to determine how best to avoid you. Give-way vessel The vessel that does not have the right-ofway has the duty to take positive and timely action to stay out of the way of the Stand-On vessel.
U6BV37E0.book Page 6 Wednesday, May 1, 2013 8:56 AM Safety information 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.
U6BV37E0.book Page 7 Wednesday, May 1, 2013 8:56 AM Safety information are passed on the starboard (right) side when proceeding from open water into port, and black buoys are to port (left) side. When navigating out of port, your position with respect to the buoys should be reversed; red buoys should be to port and black buoys to starboard. Many bodies of water used by boaters are entirely within the boundaries of a particular state.
