Sierra 118-2764 Exhaust Hose

Compatible Engines

The original Sierra 118-2764 exhaust hose is a critical component of the exhaust system, engineered to ensure durability and tightness in harsh marine conditions. Often associated with Cobra series models produced between 1986 and 1993, this specific gasket exemplifies Sierra's engineering precision. Its primary function is to isolate vibrations and compensate for relative movement between exhaust pipe segments and the boat hull, protecting the system from cracks caused by continuous mechanical stress.

Since available technical data does not provide an unambiguous list of compatible engine models, it is crucial to verify fitment by the manufacturer's catalog number 118-2764 or the original OE number. Every boat and engine has specific requirements, so we recommend a detailed comparison of numbers before purchase. If you have any doubts about whether this Sierra 118-2764 exhaust hose fits your specific drive, contact our customer support. Our experts will help you verify compatibility so you can purchase the correct part without risk of error.

Installation and Operation

Proper installation of this gasket is fundamental to the lifespan of the entire exhaust system. We recommend using only high-quality silicone lubricants that do not degrade rubber at high temperatures. Avoid over-tightening clamps, which can lead to rubber deformation and loss of seal. Regular inspection of the gasket's condition will help you detect potential cracks at an early stage, preventing expensive repairs.
