Abstract: 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.
