装置。[Claims for Utility Model Registration] An intercooler that cools the intake air of an engine compressed by a turbocharger with seawater sent by a seawater pump, and an intercooler that exchanges heat with the seawater that cooled the intake air by cooling water and exhaust gas of the engine. In a marine engine equipped with a heat exchanger for cooling, the seawater recirculation pipe branched from the seawater discharge pipe of the heat exchanger and connected to the seawater suction pipe of the seawater pump, a drainage switching valve that guides seawater to either the seawater discharge pipe or the seawater recirculation pipe; and a drainage switching valve that opens and closes the seawater suction pipe to draw either new seawater or seawater from the seawater recirculation pipe into the seawater pump. What is claimed is: 1. A warm-up promotion device for a marine engine, comprising: a water intake switching valve that guides the water to the side; and a controller that controls opening and closing of the drainage switching valve and the water intake switching valve depending on the operating state of the engine.
