Mercury – Fuel Pump Diaphragm & Gasket Kit | Fuel System Components | Composite & Rubber | 97611

Overview

Any boater who’s been out on the water at sunrise knows the quiet comfort of an engine that starts cleanly and settles into a steady rhythm. That confidence often comes down to the smallest parts—pieces you rarely see but rely on every single time you push away from the dock. The Quicksilver 97611 Fuel Pump Diaphragm and Gasket Kit brings that sense of security back to older 2-stroke Mercury and Mariner outboards. When your fuel system is sealed tight and pumping smoothly, you feel it in every crisp throttle response and easy idle.

Performance & Practical Benefits

A fuel pump might be tucked out of sight, but when the diaphragm or gaskets start to fail, you feel the effects immediately—rough idle, hesitation, stalling under load, or that soft sputter that keeps you glued to the primer bulb. Replacing these components with the Quicksilver 97611 kit restores that tight, steady fuel delivery your engine was designed for.

With fresh seals and a responsive diaphragm, you’ll notice:

• Smoother throttle transitions as the engine receives consistent fuel
• A more predictable idle, even after long runs or extended trolling
• Better starting reliability, whether warm or cold
• Reduced fuel seepage and air intrusion, two common culprits of poor performance

It’s a simple repair that brings your outboard back to feeling solid and dependable—exactly what you want when the tide is moving fast or the kids are already in the boat waiting to go.

Why Buy OEM

Fuel systems aren’t a place to gamble with off-brand parts. With this Mercury Marine part, you’re getting:

• Precision-cut components that match factory tolerances
• Materials tested specifically for marine fuel blends and temperature swings
• Long-term reliability backed by decades of Mercury engineering
• A direct, no-guesswork fit that ensures the pump seals correctly the first time
• Confidence that your outboard is protected, not patched together

Experienced boaters know—using OEM parts isn’t about brand loyalty, it’s about preventing headaches on the water.
