Universal Heat Exchanger – Marine Cooling System

This universal marine heat exchanger is a reliable second-hand cooling unit, fully inspected and ready for installation. It transfers heat efficiently between the engine’s closed-loop coolant and the raw water circuit, helping you maintain stable operating temperatures. By preventing overheating, it protects key engine components and extends their lifespan.

Built from durable, corrosion-resistant materials, this heat exchanger performs well in both saltwater and freshwater conditions. Its multiple hose connections allow flexible setup, so you can adapt it to various inboard or sterndrive marine engines without major modifications.

You can expect normal cosmetic wear from previous use, such as light surface marks or minor corrosion, yet these do not affect its performance. All fittings, mounting points, and hose connections remain solid and secure. We have tested the unit for leaks and confirmed it holds pressure under operating conditions.
