    • A marine propulsion unit (10) has a depending gearcase (12) with one or more water inlet openings (22) in the sides of the gearcase for supplying water to a water pump (20), and an auxiliary water inlet opening (32) at an anti-ventilation plate (30) above the propeller (14) for supplying additional water to the water pump (20). The water passage (42, 50) from the auxiliary water inlet opening (32) to the water pump (20) has a portion (44, 52) extending downwardly below the level of the auxiliary water inlet opening (32) and communicating with the side water inlet openings (22). When the side water inlet openings (22) are below the water line and the auxiliary water inlet (32) is above the water line, water is received in the downwardly extending portion (44, 52) of the second passage (42, 50) and blocks air from flowing from the auxiliary inlet opening (32) to the water pump (20), to prevent engine overheating.
    • 船用推进单元(10)具有在齿轮箱侧面具有一个或多个用于向水泵(20)供水的一个或多个进水口(22)的悬挂式齿轮箱(12)和辅助进水口(32) 在螺旋桨(14)上方的防透气板(30)处,用于向水泵(20)供应额外的水。 从辅助水入口开口(32)到水泵(20)的水通路(42,50)具有在辅助水入口开口(32)的水平面下方向下延伸并且与 侧入水口(22)。 当侧面进水口22位于水位线下方并且辅助水进口32位于水位线上方时,水在第二通道42,50的向下延伸部分44,52中被接收, 并且阻止空气从辅助入口开口(32)流到水泵(20),以防止发动机过热。

    • A fuel pump (14) is driven by a marine engine (12) for pumping fuel from a fuel tank (16) to the internal combustion engine (12). A cooling jacket (18) is disposed about the fuel pump (14) and is in sealing engagement with the fuel pump (14) to form a cooling chamber (20) about the fuel pump (14). The cooling jacket (18) has a water inlet (22) for admitting cooling water to the cooling chamber (20). A water pump (24) is driven by the engine (12) for supplying environmental water to the water inlet (22) of the cooling jacket (18). A pickup (26) is connected to the water pump (24) for supplying environmental marine water to the water pump (24), i.e., the pickup (26) is disposed in the water in which the watercraft is buoyed. The cooling jacket (18) has a water outlet (28) for dumping water from the cooling chamber (20) back to the environmental marine water, i.e., the water outlet (28) is disposed to dump cooling water into the same water in which the watercraft is buoyed.
    • 燃料泵(14)由用于将燃料从燃料箱(16)泵送到内燃机(12)的船用发动机(12)驱动。 冷却套(18)围绕燃料泵(14)设置并且与燃料泵(14)密封接合,以形成围绕燃料泵(14)的冷却室(20)。 冷却套(18)具有用于将冷却水引入冷却室(20)的进水口(22)。 水泵(24)由发动机(12)驱动,用于向冷却套(18)的进水口(22)供给环境水。 拾水器26连接到水泵24,用于向水泵24提供环境海水,即将拾取器26设置在船舶浮起的水中。 冷却套(18)具有用于将冷却室(20)的水倾倒回到环境海水中的出水口(28),即,出水口(28)被设置成将冷却水倾倒到相同的水中,其中 船只浮起来
