Common Concerns Answered
Will this propeller fit my outboard motor?
This propeller is designed for specific outboard engine models that match its 9 1/4 inch diameter and 12 inch pitch configuration. Always verify your engine's original propeller specifications or consult your owner's manual for compatibility before purchase.
Is aluminum a good material for propellers?
Aluminum alloy is a widely used material for propellers due to its excellent balance of durability, cost-effectiveness, and corrosion resistance. It provides reliable performance for general boating applications.
How does propeller pitch affect performance?
Pitch dictates how far the propeller would theoretically move through the water in one revolution. A 12-inch pitch, as found on this propeller, typically offers a good balance for acceleration and maintaining a reasonable top speed for smaller to mid-sized boats.
