Common Concerns Answered
Will this propeller fit my specific outboard motor?
The N4L spline configuration is critical for secure engagement with your engine's drive shaft. Always verify that your outboard motor manufacturer specifies an N4L spline type and a 12.5 x 12 pitch for optimal performance. Consult your owner's manual for precise compatibility.
How will this propeller affect my boat's speed and handling?
The 12.5-inch diameter and 12-inch pitch are designed to provide a balance between acceleration and top-end speed. Expect improved hole shot and mid-range thrust, which may slightly alter top-end RPM depending on your hull design and engine's power band.
Is aluminum the best material for this propeller?
Aluminum is a widely used and effective material for propellers, offering a good balance of strength, weight, and cost. It provides adequate durability for most recreational boating applications and offers some sacrificial protection to your gearcase in the event of impact.
Frequently Asked Questions
What is the significance of the N4L spline count?
The N4L spline count refers to the specific number and configuration of splines on the propeller's hub, ensuring it correctly mates with the forward gear splines on your outboard's drive shaft for power transfer.
How does propeller pitch affect boat performance?
Propeller pitch determines the distance the propeller would theoretically move forward in one revolution. A lower pitch (like 12 inches) generally provides better acceleration and hole shot, while a higher pitch offers higher top-end speed.
What is the diameter of this propeller?
The diameter of this propeller is 12.5 inches, measured from the tip of one blade across the hub to the tip of the opposite blade.
What material is this propeller constructed from?
This propeller is constructed from a durable aluminum alloy, chosen for its strength-to-weight ratio and resistance to corrosion in marine environments.
Where is this propeller manufactured?
This propeller is manufactured by JOHNSON PROPELLER CO., INC., a reputable producer of marine propulsion components.
