68V-9-14-1 2/20/03 14:12 Page 12 E EMU00015 BASIC BOATING RULES (Rules of the road) Just as there are rules which apply when you are driving on streets and high ways, there are waterway rules which apply when you are driving your boat. These rules are used internationally, and are also enforced by the United States Coast Guard and local agencies. You should be aware of these rules, and follow them whenever you encounter another vessel on the water.
68V-9-14-1 2/20/03 14:12 Page 13 E RULES WHEN ENCOUNTERING VESSELS There are three main situations which you may encounter with other vessels which could lead to a collision unless the Steering Rules are followed: Meeting (you are approaching another vessel head-on) Crossing (you are traveling across the other vessel’s path) Overtaking (you are passing or being passed by another vessel) In the following illustration, your boat is in the center.
68V-9-14-1 2/20/03 14:12 Page 14 E the other vessel is expected to maintain its course and speed. You must stay out of its way until you are clear of it. Likewise, if another vessel is passing you, you should maintain your speed and direction so that the other vessel can steer itself around you. OTHER SPECIAL SITUATIONS There are three other rules you should be aware of when driving your boat around other vessels.

68V-9-14-3 2/20/03 13:32 Page 15 E EMU01412 TRIMMING OUTBOARD MOTOR The trim angle of the outboard motor helps determine the position of the bow of the boat in the water. The correct trim angle will help improve performance and fuel economy while reducing strain on the engine. The correct trim angle depends upon the combination of boat, engine, and propeller. Correct trim is also affected by variables such as the load in the boat, sea conditions, and running speed.
68V-9-14-3 2/20/03 13:32 Page 16 E ADJUSTING TRIM ANGLE EMU01401 UP DN Power Trim/Tilt Model UP DN w q 000350 q DN UP 000351 8 Be sure all people are clear of the outboard motor when adjusting the trim/tilt angle, also be careful not to pinch any body parts between the drive unit and clamp bracket. 8 Use caution when trying a trim position for the first time. Increase speed gradually and watch for any signs of instability or control problems.
68V-9-14-3 2/20/03 13:32 Page 17 E EMU19160 q 001672 w Trim angle settings and boat handling When the boat is on plane, a bow-up attitude results in less drag, greater stability and efficiency. This is generally when the keel line of the boat is up about 3 to 5 degrees. With the bow up, the boat may have a greater tendency to steer to one side or the other. Compensate for this as you steer. The trim tab can also be adjusted to help offset this effect.
68V-9-14-3 2/20/03 13:32 Page 18 E NOTE: Depending on the type of boat, the outboard motor trim angle may have little effect on the trim of the boat when operating. EMU01200 TILTING UP/DOWN If the engine will be stopped for some time, or if the boat is moored in shallows, the engine should be tilted up to protect the propeller and casing from damage by collision with obstructions, and also to reduce salt corrosion. 000352 cC Before tilting the motor, follow the procedures under “STOPPING ENGINE”.
