0335547 0436609 BRP Air Silencer Assy | Genuine Used Part

🔧 Product Description

Genuine Used BRP Evinrude Johnson 90HP-115HP V4 Air Silencer Assembly - Part Number: 0436609

A genuine pre-owned BRP, OMC, Evinrude and Johnson air-silencer assembly for selected 60-degree V4 two-stroke outboards.

Catalogue correction: 0436609 is the air-silencer assembly. Part number 0335547 is a throttle cam and is not an air-silencer part, supersession or equivalent.

The air silencer mounts in front of the engine's carburettors or intake system. It reduces intake roar, protects the throttle openings and maintains the factory airflow chamber.
