A device for winterizing boats by replacement of coolant water in the engine thereof with antifreeze solution, such device including a pair of elongated substantially parallel rods having their opposite ends interconnected by clamping elements operable to vary the distance separating the rods. Each rod carries a sealing head which can be sealingly positioned over the water intake on opposite sides of the outdrive of an engine to be winterized. The sealing heads can be independently adjusted in their positions along the elongated rods. One of the sealing heads carries a fitting by means of which an antifreeze solution can be connected to the sealing head to allow the solution to be passed through the sealing head, through intake ports and into the engine to replace coolant water in the engine which is displaced through discharge ports of the engine.
