Johnson Outboard Propeller | Premium Aluminum & Stainless Steel Propellers for 2-300HP Johnson/Evinrude Outboards

Product Overview

The Johnson Outboard Propeller is designed to deliver exceptional performance, durability, and efficiency for a wide range of Johnson and Evinrude outboard engines. Available in aluminum and stainless steel variants, these propellers are engineered to optimize speed, fuel efficiency, and handling in various boating conditions—from freshwater lakes to saltwater environments.

Performance Features

✔ Optimized Blade Design: Reduces cavitation for smoother acceleration and top speed.
✔ Precision-Balanced: Minimizes vibration for quieter, more efficient operation.
✔ Multiple Pitch Options: Tailored for specific HP ranges (6–24 inches).
✔ Corrosion-Resistant: Specially treated for longevity in all water conditions.

Material & Construction

Aluminum Propellers

• Lightweight & Durable: Marine-grade aluminum alloy construction.
• Cost-Effective: Ideal for smaller engines (2–300HP).
• Sacrificial Design: Protects the lower unit from impact damage.

Stainless Steel Propellers

• High-Strength: Premium 300-series stainless steel for superior performance.
• Laser-Cut Blades: Precision-engineered for reduced drag and better fuel efficiency.
• Ideal for High-HP Engines: Perfect for 9.9HP–300HP applications.

Installation Guidelines

1. Verify Compatibility: Match the propeller to your engine’s HP, gearcase size, and OEM part number.
2. Use Proper Tools: A propeller wrench and thrust washer are recommended.
3. Torque Specifications: Follow Johnson’s guidelines to avoid damage (typically 55–75 ft-lbs).
4. Lubrication: Apply marine grease to the propeller shaft for smooth installation.

Safety & Maintenance Tips

• Regular Inspection: Check for dents, cracks, or fishing line entanglement.
• Avoid Impact: Aluminum props can bend; stainless steel may transmit shock to the drivetrain.
• Saltwater Care: Rinse with fresh water after each use to prevent corrosion.

FAQ 

Q: How do I choose the right pitch for my boat?
A: Lower pitch (6–11") for better acceleration and heavy loads; higher pitch (12–24") for top speed and lighter boats.

Q: Can I use an aluminum propeller in saltwater?
A: Yes, but rinse it thoroughly after each use to prolong its lifespan.

Q: What’s the advantage of stainless steel?
A: Greater durability, higher performance at speed, and reduced flex under heavy loads.

Q: How often should I replace my propeller?
A: Replace if damaged (e.g., bent blades, cracks) or if performance declines (vibration, speed loss).
