Common Concerns Answered
Is it difficult to find replacement hardware if I lose it?
While the included stainless steel hardware is robust, specific replacement nuts and bolts are not commonly stocked as individual parts. It is advisable to carefully manage the included hardware during installation or consider purchasing a spare set if prone to misplacing small components.
Why is this anode more expensive than generic options?
The higher initial cost reflects the superior quality of Navalloy® aluminum, adherence to military specification MIL-DTL-24779, and the proprietary 'red spot' wear indicator technology. These features offer enhanced longevity and proactive maintenance benefits that outweigh the upfront investment compared to lesser-specified anodes.
Can I use this anode in freshwater?
Yes, this Performance Metals shaft anode is specifically designed and certified for suitability in salt, brackish, and fresh water environments, providing reliable corrosion protection across all marine conditions.
Frequently Asked Questions
What type of water is this aluminum shaft anode suitable for?
This aluminum shaft anode is suitable for all water types, including salt, brackish, and fresh water, offering versatile protection.
How does the 'red spot' wear indicator work?
The patented 'red spot' is a visual indicator embedded within the anode; as the anode corrodes and wears away, the red material becomes exposed, signaling when the anode has reached a critical depletion level and requires replacement.
What hardware is included with this anode?
The anode includes stainless steel hardware, with nuts pre-pressed into the casting and bolts captured by plastic retaining washers for straightforward assembly.
What are the dimensions of this shaft anode?
The anode has dimensions of A - 2-1/4" (57mm), B - 4-1/4" (108mm), and C - 3-3/4" (95mm).
Is this anode designed for specific boat types or shaft sizes?
This anode is designed for a 2-1/4" propeller shaft diameter and is suitable for various boat types operating in all water conditions.
