Applicable vehicle models: this mixing elbow is fit for Yanmar Marine GM Series. 
Function: the exhasut mixing elbow is to mix hot engine coolant with exhaust gases before they are discharged. This process dramatically lowers the temperature of both the exhaust gases and the surrounding exhaust piping, protecting sensitive components like rubber hoses, mufflers, and fiberglass engine bays from heat damage and preventing potential fire hazards.
Enhances system reliability: a ideal replacement for damaged part that have failed due to internal corrosion clogging, external rust-through, or cracking—common issues in marine environments. This new mixing elbow restores proper cooling efficiency, prevents overheating, and ensures the safe operation of the entire wet exhaust system, avoiding costly damage to the engine and vessel.
Installation: professional installation is highly recommended.
