Restore Your Yamaha Outboard's Power with Precision

Nothing disrupts a day on the water like a sluggish Yamaha outboard engine bogging down from a faulty carburetor. Fuel delivery issues, rough idling, or hesitation under load often stem from worn diaphragms, clogged jets, or degraded gaskets. This carburetor repair kit steps in as your go-to solution, delivering fresh components to breathe new life into your 2-stroke powerhouse. Engineered for seamless compatibility, it tackles common wear points that plague marine environments—salt spray, ethanol-blended fuels, and constant vibration.

Crafted with high-grade materials like Viton for fuel resistance and precision-machined brass fittings, this kit ensures reliable sealing and flow. Boaters swear by it for quick fixes that match or exceed factory performance, getting you back to smooth acceleration without the hassle of sourcing individual parts.

Key Components for a Complete Rebuild

• Diaphragms: Flexible, ethanol-resistant membranes that maintain consistent fuel metering, preventing lean spots or flooding.
• Gaskets and O-rings: Custom-fit seals that eliminate vacuum leaks, a frequent culprit in hard starts.
• Needle and seat assemblies: Polished for optimal shutoff, ensuring precise fuel control even after prolonged storage.
• Float assemblies: Lightweight and durable, they keep fuel levels steady for reliable operation at all RPMs.
• Screens and jets: Fine-mesh filters and orifices to combat debris buildup from dirty tank water or old gas.

Every piece is individually inspected for quality, making this kit ideal for DIY mechanics or seasoned techs aiming to minimize downtime during peak boating season.

Perfect Fit for Popular Yamaha Models

Designed specifically for Yamaha 40HP to 70HP 2-stroke outboards from the mid-80s through the 2000s, this kit covers a wide range of carburetors including PT, PZ, and similar series.

Step-by-Step Installation Tips

Reviving your carb doesn't require a shop lift. With basic tools—a carb cleaner spray, small screwdrivers, and compressed air—you can complete the job in under an hour per carb.

1. Disconnect fuel line and throttle linkage; drain float bowls.
2. Remove carb from manifold, noting gasket orientation.
3. Disassemble carefully, soaking in cleaner; inspect bores for wear.
4. Replace all soft parts first—diaphragms and gaskets—then seats and needles.
5. Reassemble with fresh bowls, sync floats, and bench-test for leaks.
6. Reinstall, prime, and fire up—adjust idle if needed.

Pro Tip: Always replace fuel lines and filters alongside for a total refresh. Run Sea Foam through the system post-install to clear residues.
