Marine Wet Exhaust Systems
Water is injected into the exhaust system to cool the gasses, which are then passed through the outlet. The injected water lowers the temperature of the exhaust gasses from as high as 2000ºF to below 250°F. This cools the gasses sufficiently enough for the use of flexible silicone hose. The water-cooled exhaust does not cause a fire hazard, and needs no insulation.
Advantages of Silicone:
- Easier to run than rigid pipe
- Not subject to corrosion, stress or cracking Absorbs engine movement and vibration
