Common Concerns Answered
Will this propeller cause excessive vibration?
The N4r series is engineered for precise balance, minimizing vibration for a smoother operation. Proper installation and engine alignment are crucial for optimal performance.
Is this propeller suitable for saltwater use?
Yes, this propeller is constructed from a high-strength aluminum alloy specifically chosen for its corrosion resistance in marine environments, including saltwater.
How does the 4-blade design affect performance?
A 4-blade propeller typically offers improved acceleration and better grip in the water, especially during aggressive maneuvers or when carrying heavier loads. This can result in a better hole shot and more consistent performance.
Frequently Asked Questions
What is the recommended application for a 13.7 x 17 prop?
A 13.7 x 17 propeller is generally suited for outboard engines in the 90-200 horsepower range, providing a balance of speed and thrust for various hull types.
How do I confirm the 1 1/8 inch shaft fitment?
Verify your engine's propeller shaft diameter by consulting your engine's service manual or measuring the shaft diameter directly. A 1 1/8 inch shaft is a common size for many mid-range outboards.
What does the 'N4r' designation signify?
The 'N4r' designation typically indicates a specific blade design optimized for performance characteristics like reduced cavitation and improved efficiency, often associated with Johnson Propeller Co., Inc.'s advanced propeller lines.
Can I use this propeller if my current one is a 3-blade?
Yes, switching from a 3-blade to a 4-blade propeller with the same pitch and diameter can offer improved hole shot and mid-range acceleration, though top-end speed might be marginally affected.
What maintenance is required for this aluminum propeller?
Regular inspection for nicks, dents, or bends is recommended. Clean the propeller after use, especially in saltwater, and apply a marine lubricant to the shaft splines during installation to prevent seizing.
