Common Concerns Answered
Will this propeller fit my outboard motor?
This 12.5" x 13" A3r propeller is designed as a direct replacement for specific BRP (Evinrude/Johnson) outboard models. Always verify fitment against your outboard's documentation or consult a marine specialist to ensure compatibility before purchase.
How does an aluminum propeller compare to a stainless steel one?
Aluminum propellers are a cost-effective option, providing good performance for general use. They are more prone to damage from impacts than stainless steel but offer a sacrificial advantage, absorbing minor impacts to protect the lower unit gears.
What is the significance of the 13-inch pitch?
A 13-inch pitch indicates that for one revolution of the propeller, it would theoretically move the boat 13 inches forward. This pitch is generally suitable for smaller to medium-sized boats, balancing top-end speed with acceleration.
