Common Concerns Answered
Will this propeller fit my outboard?
The 'A3r' hub system is designed to fit specific outboard engine splines. Always verify compatibility with your engine's propeller shaft by consulting your outboard's manual or our fitment guide before purchase.
How does an aluminum propeller compare to stainless steel?
Aluminum propellers like this one offer a cost-effective solution and are generally lighter. While durable, they are more susceptible to damage from underwater impacts compared to stainless steel, often sacrificing themselves to protect the lower unit.
What is the significance of the pitch?
The 12-inch pitch on this propeller determines how far it moves the boat forward with each revolution. A lower pitch, like 12 inches, typically provides better acceleration and top-end speed for lighter craft, while a higher pitch prioritizes top speed for heavier loads.
