Abstract
An apparatus for separating solid material from cooling water in the cooling system of the engine block of a marine engine. The engine block comprises a plurality of cylinder bores surrounded by a cooling passage through which cooling water is pumped. The bottom portion of the block includes a drain outlet that communicates with the cooling passage and a tubular separating member has a first generally horizontal section that is sealed within the drain outlet. The tubular separator also includes a second section that is located within the cooling passage and extends downwardly from the inner end of the first section and is located between two adjacent cylinder bores. The lower end of the second section is closed and a port is provided in the side of the second section adjacent the closed end and facing toward one of the cylinder bores. The outer end of the first section of the tubular member, which is located on the exterior of the block, is connected through a suitable hose or conduit to an automatic drain valve which is located at a level beneath the engine block. When the ambient temperature falls beneath a selected value, the drain valve will open and water will drain from the e…
