An apparatus is disclosed for use in flushing the cooling systems of water cooled outboard and inboard/outboard motorboat engines that draw cooling water through intakes in the engine housing beneath the surface of the water in which the boat is operating. The apparatus allows lubricant to be injected into the cooling system after the cooling system has been flushed with clean, fresh water to leave a coating of oil in the surfaces of the cooling system to prevent rust from forming on the surface. The apparatus consists of a U-shaped or bighted spring with two legs on which are slidably mounted two cup-shaped seal members constructed of elastomeric material. The seal members are positioned over the cooling intakes of the engine housing. One of the seal members has an opening through which clean fresh water is introduced and the other sealing member has an opening through which lubricant is injected.
