67C-15373-00-00 Yamaha Hose | Genuine Used Part

🔧 Product Description

Genuine Yamaha Crankcase Breather Pipe - Part Number: 67C-15373-00-00

A genuine Yamaha moulded crankcase breather pipe for selected F30 and F40 carburetted four-stroke outboards.

The supplied component is catalogued by Yamaha as a breather pipe rather than a general-purpose hose. It routes crankcase vapours into the intake silencer so they can be drawn back into the engine and burned.

🔌 Function

The pipe carries crankcase blow-by vapours from the engine into the intake silencer. Recycling these vapours reduces external oil mist and allows the vapour to be burned during combustion.

⚠️ Common Signs of Failure

• Hose is split, hardened or collapsed
• Oil mist appears around the crankcase vent
• Engine draws unmetered air through a cracked pipe
• Hose rubs against nearby engine components
• Pipe disconnects because the retaining clip is missing
