Common Concerns Answered
Will this propeller fit my 115hp outboard?
This Polaris S4R propeller is specifically engineered for 115hp outboards with a 15 1/4 inch diameter and 22 inch pitch. Verify your engine's specific propeller fitment requirements before purchase.
How durable is a stainless steel propeller compared to aluminum?
Stainless steel propellers offer superior strength, corrosion resistance, and impact durability compared to aluminum, leading to a longer service life and better performance retention in saltwater and abrasive environments.
What is the advantage of a four-blade propeller?
A four-blade propeller typically provides improved acceleration, better load-carrying capacity, and reduced vibration for a smoother ride, often at the cost of marginal top-end speed compared to a three-blade of similar pitch.
Frequently Asked Questions
What is the recommended application for a 15 1/4x22 S4R propeller?
This propeller is optimized for 115hp engines, offering enhanced hole-shot and mid-range acceleration, suitable for boats that require efficient planing and cruising performance.
How does the 22-inch pitch affect performance?
A 22-inch pitch allows the engine to reach higher RPMs at wide-open throttle, contributing to increased top-end speed on suitable hulls and load conditions.
Can this propeller be used in saltwater environments?
Yes, its high-strength stainless steel construction provides excellent resistance to corrosion, making it ideal for saltwater use.
What is the expected lifespan of this propeller?
With proper care and maintenance, a stainless steel propeller like this Polaris S4R can last for many years, significantly longer than an aluminum equivalent, especially in harsh marine conditions.
Does this propeller require a specific hub kit?
Propeller hub kits are typically sold separately and vary based on the outboard engine's drive system. Please consult your engine's manual or our fitment guide to select the correct hub kit.
