Wet Exhaust Hose for Boats Marine exhaust hoses are key components in a marine exhaust system. They can be used as flexible connectors to circulate, transfer and cool engine water. These hoses are easy to install and offer excellent vibration dampening compared to rigid piping or tubing. Marine wet exhaust hoses are particularly effective because they mix seawater with exhaust gases. The seawater is injected into the exhaust stream to cool the exhaust gases, thereby significantly reducing the temperature of the exhaust gases before they leave the vessel. Key Features of Marine Exhaust Hose DURABLE AND FLEXIBLE: Designed to withstand the marine environment, these hoses are durable and flexible, making installation a breeze. High Temperature Resistance: Our hoses are able to withstand high temperatures, thus ensuring the safe discharge of exhaust gases. Corrosion Resistant: Made from materials such as rubber and silicone, they resist corrosion from salt water and other harsh environments.
