Description
15x12 N4L Propeller | Boat Supply Store
This 15x12 N4L propeller from Michigan Wheel is engineered to maximize thrust and efficiency for smaller outboard applications. It features a durable aluminum construction with a 1 1/8 inch bore and a 0.150 inch cup depth, directly translating engine power to water movement for improved hole shot and top-end speed. This propeller is ideal for bay boats operating in the shallow flats of the Gulf Coast or for pontoon boats requiring consistent performance in freshwater environments.
Key Features
- Maximize thrust with a 15-inch diameter and 12-inch pitch configuration.
- Ensure robust power transfer via a precisely machined 1 1/8 inch propeller bore.
- Enhance grip and reduce slip with a 0.150 inch cup depth.
- Durable aluminum construction for longevity in marine environments.
- Designed for optimal performance on smaller outboard engines.
- Facilitate easy installation with standard shaft compatibility.
- Engineered for efficient hole shot and improved cruising speeds.
- N4L series provides reliable performance characteristics.

Common Concerns Answered
Will this propeller fit my outboard motor?
This propeller features a standard 1 1/8 inch bore, designed to fit a wide range of outboard motors with compatible propeller shafts. Always verify your engine's specific propeller shaft size before purchase.
Is this propeller suitable for saltwater use?
While constructed from durable aluminum, it is essential to properly clean and flush the propeller after saltwater exposure to prevent corrosion and maintain optimal performance.
How will this propeller affect my boat's speed?
The 15x12 pitch is engineered to provide a balance between acceleration and top-end speed. Expect improved hole shot and potentially a slight increase in cruising speed over a smaller diameter or lower pitch propeller.
Frequently Asked Questions
What is the significance of the 'N4L' designation?
The 'N4L' designation typically refers to a specific propeller series from Michigan Wheel, indicating a particular design and performance characteristic optimized for certain engine applications.
What does the 0.150 inch cup depth do?
The 0.150 inch cup depth helps the propeller 'bite' into the water more effectively, reducing cavitation and slippage, which results in better thrust and efficiency, especially during acceleration.
Is this a direct replacement for my original propeller?
With a 1 1/8 inch bore, it is designed as a common fit. However, it is crucial to confirm your engine's specific requirements match the diameter, pitch, and bore size of this propeller.
What type of boat is this propeller best suited for?
This 15x12 N4L propeller is well-suited for smaller aluminum fishing boats, skiffs, jon boats, and some pontoon boats powered by outboards in the 40-70 HP range, depending on the specific engine manufacturer's recommendations.
Can I use this propeller on a different pitch than my current one?
Changing propeller pitch can alter your boat's performance characteristics. A higher pitch generally increases top speed but reduces acceleration, while a lower pitch improves acceleration at the cost of top speed. Always consult your engine's performance chart or a marine professional.
