- Rotation (R): These propellers are designed for right-hand rotation, making them compatible with most Mercury and Yamaha engines in this horsepower range.
Propeller Specifications for 6-15HP Engines
Engine Compatibility
For engines in the 6-15HP range, these propellers are designed to fit 2-stroke and 4-stroke engines, with a gearcase size of 2-1/2 inches. They are compatible with engines manufactured from 1986 and onward, offering a perfect fit for a variety of boat types and marine conditions.
Key Specifications:
| OEM # | Blade Count (B) | Diameter (D) | Pitch (P) | Rotation (R) |
|---|---|---|---|---|
| / | 3 | 9.25 | 8 | Right |
| / | 3 | 9.25 | 9 | Right |
| / | 3 | 9.25 | 10 | Right |
| / | 3 | 9.25 | 11 | Right |
| / | 3 | 9.25 | 12 | Right |
- Blade Count (B): Like the 4-6HP models, these propellers also feature 3 blades, providing excellent performance while keeping the boat stable and responsive in a variety of water conditions.
- Diameter (D): The diameter for this range is consistent at 9.25 inches, which ensures greater thrust for engines producing more power, while still maintaining fuel efficiency.
- Pitch (P): The pitch for these models ranges from 8 inches to 12 inches, giving you options depending on your specific needs. A lower pitch offers better thrust, while a higher pitch allows for higher speeds.
- Rotation (R): All these models are designed for right-hand rotation, making them compatible with most 6-15HP Mercury and Yamaha engines.
Understanding the Features: Why Choose Stainless Steel Propellers?
Choosing stainless steel for your boat's propeller comes with several advantages, especially for 4-15HP Mercury engines:
- Corrosion Resistance: Stainless steel is highly resistant to corrosion, which is especially important for boats used in saltwater environments. These propellers are designed to withstand the harsh marine conditions, ensuring they last longer than their aluminum counterparts.
- Strength and Durability: Stainless steel is more robust than aluminum, making these propellers less prone to damage from debris or impacts. This makes them an ideal choice for boaters who frequently navigate through rougher waters or need reliable performance in challenging conditions.
- Performance Efficiency: Stainless steel propellers offer a higher level of precision and rigidity. This results in better power transfer from the engine to the water, improving both fuel efficiency and speed. The smooth operation of stainless steel propellers also reduces engine strain and vibrations.
- Better Handling: With their durable construction and optimized design, stainless steel propellers provide superior thrust, resulting in more responsive handling and improved stability when operating at high speeds.
Conclusion
When selecting a propeller for your 4-15HP Mercury engine, it's crucial to consider factors such as blade count, diameter, pitch, and rotation. Our stainless steel propellers offer the ideal balance of performance, durability, and efficiency, ensuring that your boat runs smoothly and efficiently, whether you're cruising on calm waters or tackling more challenging conditions.
These propellers are designed for engines from 1999 onward and fit a wide range of Mercury models, from 4HP 2-stroke to 15HP 4-stroke engines.
