663-14945-00 – Jet – Yamaha Outboard

The 6631494500 jet is a genuine Yamaha OEM fuel jet that helps control how much fuel flows into your outboard engine’s carburetor. This small component meters fuel as air moves through the carburetor. In doing so, it helps your engine get the proper fuel-to-air mixture it needs for efficient combustion. Because it comes from Yamaha, it fits precisely in compatible carburetor assemblies.

This jet works in the intake and carburetor system of many Yamaha outboards. Furthermore, the part threads into the carburetor bowl and forms a calibrated opening for fuel delivery. It plays a key role in throttle response and overall engine performance. If your engine runs too rich or too lean, changing jets can improve running quality and reduce flat spots.

Also, using the correct OEM jet makes tuning easier. Genuine jets match the exact size and thread pattern Yamaha designed. Therefore, you avoid guesswork and don’t need modifications. Moreover, a fresh jet helps support more stable idle and smoother acceleration across RPMs.

Whether you’re rebuilding an older carburetor or correcting fuel delivery issues, this jet gives you reliable metering. It fits in standard carburetor setups and installs in minutes with basic tools.
