Sierra 18-7215

Revitalize your outboard motor's performance with the Sierra 18-7215 Carburetor Kit, a reliable rebuild solution designed for Mercury engines. This kit, cross-referenced as MC#1395-9024, tackles common fuel delivery issues that plague older marine carbs, restoring smooth idling, crisp throttle response, and efficient fuel economy. Boat owners swear by Sierra parts for their spot-on fit and longevity, making this an essential upgrade for weekend warriors and serious anglers alike.

Why Choose the Sierra 18-7215 for Your Mercury Outboard?

Unlike stock replacements that wear out quickly in salty environments, this kit features corrosion-resistant gaskets, precision-machined needles, and high-quality floats that stand up to ethanol-blended fuels. It's not just a patch job—it's a full rebuild that breathes new life into carbs showing signs of varnish buildup, erratic running, or hesitation under load. Save time and frustration by avoiding full carb replacements; this kit gets you back on the water faster.

Precision Components for Peak Performance

• Viton-tipped needles and seats: Seal perfectly to prevent leaks and flooding, even after prolonged storage.
• Brass accelerator pumps: Deliver instant power without the lag common in worn-out units.
• Rebuild-ready assortment: Includes diaphragms, gaskets, and O-rings tailored for MC-1395-9024 specs.
• Anti-corrosion coatings: Protect against marine moisture and extend service intervals.

Perfect Fit for Popular Mercury Models

This kit slots right into a range of Mercury 2-stroke outboards, from 40hp to 115hp models spanning multiple years. Verify your carb's markings match MC#1395-9024 or equivalents like 1395-9024 for seamless compatibility. It's a go-to for 50hp, 60hp, and 70hp engines where fuel atomization is key to avoiding bogging down during takeoff.

Step-by-Step Rebuild Tips for DIY Success

1. Drain fuel and remove the carb—label hoses to simplify reassembly.
2. Disassemble carefully, noting float height settings (critical for proper fuel level).
3. Clean passages with carb cleaner and compressed air; skip the wire— it enlarges jets.
4. Install new kit parts per diagram—double-check needle valve orientation.
5. Bench-test for leaks before reinstalling, then sync with other carbs if multi-unit setup.

Pro tip: Always replace fuel lines and filters during rebuilds to prevent debris from undoing your work. Expect 30-60 minutes per carb for experienced hands.

Long-Term Maintenance to Keep It Running Strong

Fuel stabilizers are your best friend—use them religiously to combat gum-up from modern gas. Annual inspections catch wear early, and this kit's durable materials mean rebuilds every 2-3 seasons under heavy use. Pair with fresh spark plugs for that factory-fresh roar.
