Yamaha - Float Chamber Body - Carburetor Fuel Bowl - 63V-14980-00-00

Overview

The float chamber body is where fuel sits before it’s fed into the engine, so if this part isn’t right, nothing else will be either. I’ve worked on carbs where corrosion or damage in the bowl caused constant fuel issues that no adjustment could fix. It needs to hold fuel steady and seal clean, or you’ll be chasing problems all day. When it’s in good shape, the carb runs smooth and predictable like it should.

Key Features

• Fuel Reservoir Design – Holds and regulates fuel supply within the carburetor system.
• OEM Fitment – Built to Yamaha specifications for proper sealing and alignment.
• Leak-Resistant Construction – Helps maintain a secure seal when paired with the correct gasket.
• Durable Material Build – Designed to withstand fuel exposure and marine conditions.

Engine & Boat Compatibility

Fits Yamaha outboard engines equipped with carbureted fuel systems. Commonly used on small- to mid-range horsepower outboards across fishing boats, tenders, and recreational vessels.
