摘要： In a personal watercraft with an engine 17 disposed at a central portion of a craft body and a water jet propeller 18 disposed at a stern of the watercraft, a propeller shaft 33 of the water jet propeller is connected to an end 31 of a crankshaft of the engine by a shaft coupling 32. The shaft coupling as well as the ends of the crankshaft and propeller shaft are covered from the top and from both sides with a cover apparatus 22, including a first cover section 35 for removable attachment to the engine or the hull, and a second cover section section 36 for removable attachment to the first cover section. When the cover is removed, it only of the second cover section section, and even if the space for working is small, not much time is required for removal and re-attachment thereof.

摘要： A screen for attachment to an front forked portion of a motorcycle has improved aerodynamic characteristics. An upper garnish is located on the forward side of the screen. The upper garnish extends substantially horizontally across the screen. An expanded portion protrudes forwardly and extends substantially across the entire length of the upper garnish. The expanded portion redirects any horizontal air current impacting thereagainst. The redirected air current influences the horizontal air currents impacting the screen by causing a turbulence area slightly in front of the screen. This turbulence acts to lessen the impact of the horizontal air currents against the screen, resulting in a decrease in an overall running resistance of the motorcycle.
摘要翻译：用于附接到摩托车的前叉部的屏幕具有改善的空气动力特性。上装饰物位于屏幕的前侧。上装饰件基本上水平延伸穿过屏幕。扩展部分向前突出并且基本上延伸穿过上部装饰的整个长度。扩展部分重定向影响其的任何水平气流。重定向的气流通过使湍流区域稍微在屏幕前方影响影响屏幕的水平气流。这种湍流起着减轻水平气流对屏幕的影响的作用，导致摩托车的整体行驶阻力降低。
