The Mercruiser Inboard Water Pump is a durable marine pump designed for efficient cooling in inboard engines. It ensures reliable water circulation to prevent overheating during operation. Ideal for marine applications, it offers long-lasting performance and easy maintenance.

The Mercruiser Inboard Water Pump typically features a size range of 1.5 to 2.5 inches in diameter, depending on the model. It is constructed from high-grade materials such as stainless steel, aluminum, or composite polymers for corrosion resistance. The viscosity rating is optimized for marine coolant or raw water, usually between 5W-30 or 10W-30 for lubricated models. Buoyancy is not a primary specification as it is a fixed component. The pump is designed to meet marine-grade standards for durability and performance in saltwater or freshwater environments.
