Cooling water intake with increased flow

摘要

A marine propulsion system (10) with a depending gear case (20) having water inlet openings (32 and 34) is provided with water intake plates (62 and 64) covering the water inlet openings (32 and 34) and having outer forward lips (66 and 68) spaced forwardly and outwardly of the water inlet openings (32 and 34) and outwardly of tapered gear case sections (36 and 38) leading to such openings. The water intake plates (62 and 64) define with the gear case (20) entrance cavities (70 and 72) around the water inlet openings (32 and 34), trapping additional water and directing same inwardly into the water inlet openings (32 and 34) for increasing water flow to a transverse passage (30) and to the water pump (16).
