Yamaha FX140 / FX HO / FX Cruiser OEM Exhaust Waterbox Muffler – Genuine WaveRunner 4-Stroke Water Box

Item Overview:
Genuine OEM Yamaha aluminium exhaust waterbox (water lock muffler), removed from a running Yamaha FX140 four-stroke WaveRunner. Reduces exhaust noise and traps water to stop it running back into the engine. Solid with no cracks or leaks; surface marks from age as pictured.

Why you might need this:
A cracked, corroded or leaking waterbox can let water back up into the exhaust and engine after capsizing or on shutdown, cause a loud or raspy exhaust note, exhaust fumes in the hull or water in the bilge. Aluminium waterboxes often corrode through – this is a straight OEM replacement.

OEM Part Number:
No part number visible in photos – original Yamaha FX140 waterbox.
