Abstract
A marine drive has an open loop cooling system for cooling various engine components using water drawn from the body of water in which an associated watercraft is operating. A water inlet of the cooling system has a filter cover which includes a series of apertures through which water can flow. The apertures have a maximum cross-sectional width. After passing through the water inlet, cooling water is pressurized and directed to an engine coolant passage to cool engine components. A pilot water passage branches off of the engine coolant passage and delivers cooling water through peripheral engine components to cool the components. The pilot cooling water is discharged from the marine drive in a pilot water stream that is visible to the operator of the watercraft. No portion of the pilot water passage has a diameter that is less than the maximum dimension of the water inlet filter cover openings.
