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);

t) Changed "diameter is 9:65 mm" to "diameter is 9:6 mm" (see A:5, 4:6 of the:2003 edition);

u) Changed "greater than the value specified in 9:3:2" to "greater than 9000N" (see A:6, 4:7 of the:2003 edition):

This document is modified to adopt ISO 10592:2022 "Remote hydraulic steering systems for small craft":

This document has the following structural adjustments compared to ISO 10592:2022:

---3:17 corresponds to 3:17:1 and 3:17:2 in ISO 10592:2022;

--- Chapter 6 corresponds to Chapter 7 of ISO 10592:2022;

--- Chapter 7 corresponds to Chapter 8 of ISO 10592:2022;

--- Chapter 8 corresponds to Chapter 9 of ISO 10592:2022, in which:

- 8:2:2 a)~b) correspond to 9:2:2:1~9:2:2:2 in ISO 10592:2022;
