Common Concerns Answered
Will this propeller fit my outboard motor?
This propeller features an N4L spline count, which is critical for compatibility. Always verify your outboard's specific spline requirement before purchasing to ensure proper engagement with the drive shaft.
How does a 4-blade propeller differ from a 3-blade?
A 4-blade propeller generally offers improved acceleration, better grip in rough water, and reduced vibration compared to a 3-blade, often at the expense of a slight reduction in top-end speed.
Is the N4L spline configuration common?
The N4L spline is a specific configuration designed for certain outboard models. It is essential to consult your engine's service manual or a qualified marine technician to confirm if N4L is the correct spline for your application.
Frequently Asked Questions
What is the diameter of this propeller?
The diameter of this propeller is 13.7 inches.
What is the pitch of this propeller?
The pitch of this propeller is 17.5 inches.
How many blades does this propeller have?
This propeller features a 4-blade design.
What does 'N4L Spline' refer to?
