Mercury – Quicksilver 83181 Inlet Needle and Seat | Mercury & Mariner 40–150HP 2-Stroke Outboards | 83181

Overview

If your motor’s running rich, flooding, or just not idling right, it might be time to freshen up the carb. The Quicksilver 83181 Inlet Needle and Seat Kit gives your Mercury or Mariner 40–150HP 2-stroke outboard the precise fuel control it needs to run clean and smooth again.

This factory-spec kit includes the needle, seat, and O-ring, all made to Mercury’s exact tolerances. It stops leaks, restores steady fuel flow, and helps your carb do its job the way it did when the motor was new.

Performance & Real-World Benefits

The 83181 kit brings your carb back to life by tightening up the parts that meter fuel into the engine. A worn needle or seat can cause fuel to leak past, flooding the motor or making it stumble at idle.

Once replaced, you’ll feel the difference — easier starts, smoother idle, and crisper throttle response. It’s a small, inexpensive part that can make your whole outboard feel brand new again.

Why Choose OEM

Mercury’s OEM kits are built for precision. Aftermarket versions often use softer metals or off-size parts that don’t seal correctly and wear out fast.

A genuine Quicksilver kit gives you factory-level fit, performance, and peace of mind that the job’s done right the first time.
