Frequently Asked Questions
What is the purpose of a shaft anode?
A shaft anode, also known as a P-bracket anode or propeller shaft anode, is a sacrificial metal component designed to corrode preferentially over the propeller shaft and other underwater metal fittings, thereby preventing galvanic corrosion and protecting critical drivetrain components.
What type of water is this aluminum anode suitable for?
This Performance Metals aluminum anode is specifically formulated and manufactured to be suitable for use in salt, brackish, and freshwater environments, providing comprehensive protection regardless of your operating location.
How do I know when to replace this anode?
This anode features a patented 'red spot' wear indicator. When the indicator is fully exposed or significantly diminished, it signifies that the anode has been substantially consumed and requires replacement to maintain effective corrosion protection.
What hardware is included with this anode?
This anode includes two-piece construction with stainless steel hardware. The nuts are pressed into the casting, and the bolts are captured with plastic retaining washers to facilitate easier assembly.
What are the dimensions of this anode?
The key dimensions are: Shaft Diameter (A) is 1-1/4" (32mm), the overall length (B) is 2-1/4" (57mm), and the width (C) is 2-1/2" (64mm).
