Product Details

The Sierra International 18-7834 is a replacement fuel pump diaphragm engineered for small-displacement Yamaha and Mercury outboard engines. This diaphragm is a critical internal component of the mechanical fuel pump, responsible for drawing fuel from the tank and delivering it consistently to the carburetor. Sierra's marine-grade construction ensures reliable performance in demanding on-water conditions.

Key Features:

  • Direct-fit replacement diaphragm for Yamaha and Mercury outboard fuel pumps
  • Meets or exceeds original equipment manufacturer (OEM) specifications
  • Compatible with Yamaha 2-stroke 4 HP (1984–1999) and 5 HP (1984–2002) outboard engines
  • Compatible with Mercury 2B, 4A, and 5C outboard engines
  • Replaces OEM part numbers: Yamaha 6E0-24471-00-00 and Mercury Marine 91748M
  • One fuel pump diaphragm included per package

Sierra International is a trusted name in marine replacement parts, delivering components that are purpose-built to restore proper fuel delivery and keep your outboard running at peak performance. This diaphragm is also sold as part of the Sierra 18-7368 fuel pump kit for a complete pump rebuild.

I ordered a set of in track vent visors for my truck. I ordered them on a Sunday, so it wasnt processed till Monday. The confirmation hit my email immediately though. And the visors were at my house by Thursday morning. Plus they give you $5 back just to write a review. I'll use them again.

I like
