Mercury – Composite Carburetor Float | Fuel System Component | Composite Material | 9594

Overview

If you’ve run a classic Mercury two-stroke for any length of time, you know how much personality these engines have—and how quickly they’ll tell you when something’s off in the carburetor. A sticking float, a worn pivot, or a fuel level that just won’t stay where it should can turn a smooth day on the water into constant fiddling. That’s why a dependable replacement like the Quicksilver 9594 Composite Float brings such peace of mind. It restores that clean, predictable fuel delivery you can feel every time the engine settles into a steady idle or jumps onto plane without hesitation. It’s the kind of small but important part that keeps your outboard running like it should, so you can focus on the water instead of the wrench.

Performance & Practical Benefits

A correctly functioning carburetor float affects the way your engine feels at every throttle position. With the Quicksilver 9594 installed, you’ll notice:

• Smooth, predictable idle without loading up or bogging
• Steady mid-range power, thanks to accurate fuel metering
• Clean acceleration that feels tight and responsive
• Reduced flooding or lean conditions that can cause hesitation or poor starting
• Consistent performance across varying fuel temperatures and conditions

The composite material is especially useful for modern ethanol-blended fuels, resisting swelling or sinking the way older cork or foam floats sometimes do.

Why Buy OEM

When it comes to fuel system components, precision matters. An incorrect float height or improper float material can throw the whole carburetor off balance.

Choosing Mercury OEM gives you:

• Exact fitment designed for your outboard’s carburetor
• Reliable operation that matches factory specifications
• Long-lasting durability, even in harsh marine environments
• Better fuel control and fewer performance issues
• The confidence of using parts engineered specifically for Mercury engines

It’s a smart, practical investment for anyone maintaining a classic two-stroke.
