j) Added "Requirements for Steering System" (see Chapter 6); k) Added specific requirements for installation piping (see Chapter 7, see Chapter 8 of the:2003 edition); l) Changed "The selection of steering wheel and axle should be coordinated with each other, and the common configuration is shown in Figure 3" to "The selection of steering wheel and axle should be coordinated with each other, and the common configuration is shown in Figure 3" Mutually coordinated, the general configuration diagram is shown in Appendix B, as shown in Figure B:1" (see 7:10, Appendix B, 8:5 of the:2003 edition); m) Changed the test contents to "installation verification test", "system application test" and "steering system component test" and added detailed tests Content (see Chapter 8, Chapter 9 of the:2003 edition); n) Added "steering wheel with maximum diameter Ds and deepest concave disc that can be used for hydraulic tiller" (see Chapter 9); o) Added the following content: “Recommended steering wheels with maximum diameter Ds and deepest concave discs that can be used for hydraulic steering devices (as shown in Figure 3)” capacity (see Chapter 10); p) "Slogan" and "Part Marking" have been deleted (see Chapter 12 and Chapter 13 of the:2003 edition); q) Changed the following: “The rudder stop on the outboard engine should allow an angular displacement of at least 30° to either side: The design torque on the rudder stock should be sufficient to Sufficient to move the tiller from side to side (30° port to 30° starboard or vice versa) in not more than 30 seconds: The rudder stop device should allow an angular displacement of at least 30° from the center to both sides" (see A:1, 4:1 of the:2003 edition); r) Added “providing space for the connection of steering components as shown in Figures A:3, A:4 and A:5” [see A:2b), Figures A:3, Figures A:4 and A:5]; s) Changed "greater than the value specified in 9:3:1" to "greater than 9000N" (see A:4, 4:5 of the:2003 edition);
