Anodes & Zinc Replacement for Boats & Yachts
Hull2Prop provides professional anode inspection, replacement, and supply services for boats, yachts, commercial vessels, and other watercraft throughout our Florida service areas.
Sacrificial anodes, commonly referred to as zincs, protect underwater metal components from galvanic corrosion. Regular inspection and replacement of anodes is an important part of routine underwater vessel maintenance.
Hull2Prop can inspect and replace anodes while a vessel remains in the water when appropriate, or supply replacement anodes for customers who prefer to install them during a haul-out or perform the installation themselves.
In addition to our underwater installation services, Hull2Prop supplies and sells a wide range of marine anodes from established manufacturers.
Why Are Anodes Important?
Sacrificial anodes are designed to corrode in place of more important underwater metal components.
When different metals are exposed to an electrically conductive environment such as seawater, galvanic corrosion can occur. Properly selected and installed sacrificial anodes help protect components such as propellers, shafts, rudders, trim tabs, thrusters, and other underwater metal hardware.
Because anodes gradually deteriorate as they perform their protective function, they must be inspected periodically and replaced when they are sufficiently depleted.
Anodes are not a “set it and forget it” component. Their condition can vary significantly depending on the vessel, location, water chemistry, electrical systems, and other factors.
How Long Do Anodes Last?
Anode lifespan varies depending on the vessel, location, water conditions, electrical environment, type and size of anode, and the amount of underwater metal being protected.
As a general guideline, marine anodes commonly last approximately 6 to 12 months, although actual service life can be shorter or longer depending on the vessel and operating environment.
Vessels in areas with higher electrical activity, significant marine growth, or other environmental factors may experience faster anode depletion.
For this reason, anodes should be inspected regularly rather than replaced solely according to a fixed calendar schedule.
Hull2Prop inspects anodes during routine underwater cleaning services and replaces when appropriate.
Underwater Anode Replacement
Hull2Prop supplies marine anodes from established manufacturers and maintains relationships with multiple manufacturers and suppliers.
Propellers & Shafts
Anodes installed on propeller shafts and related running gear help protect underwater metal components from galvanic corrosion.
Rudders & Trim Tabs
Rudder and trim tab anodes help protect these underwater metal components and should be inspected regularly.
Thrusters
Bow and stern thrusters can contain multiple underwater components that require appropriate anode protection.
Other Underwater Components
Hull2Prop can also inspect and replace anodes on other underwater hardware when appropriate for the vessel.
If an anode requires specialized installation, unusual hardware, or access that cannot be safely completed in-water, Hull2Prop can discuss the appropriate service or haul-out requirements with the customer. This is typically only applicable for weld-on anodes, which are rarely seen on recreational vessels, and predominately present on commercial hulls.
Anode Supply & Sales
Hull2Prop is also an anode supplier and distributor, providing marine anodes to vessel owners, boatyards, marine businesses, and other customers.
Marine Anode Brands

Other Anode Manufacturers
Hull2Prop can also source anodes from other established manufacturers based on vessel requirements, availability, and application.
If you are unsure which anode your vessel requires, contact Hull2Prop with your vessel make, model, year, and current anode information and our team can help identify the appropriate replacement.
What are Anodes?
While commonly referred to simply as “zincs,” sacrificial anodes are in fact available in several different alloys. Alloys include: aluminum, magnesium and zinc, although the latter is the most common. Anodes work to protect a vessel’s metal hardware from stray current and electrolysis damage in any marine setting. Depending on a vessel’s bonding system, and the levels of stray current around the vessel, anode life varies greatly. In situations where there are large levels of stray current around a vessel, anodes can last a matter of weeks. Anodes on a vessel with little to no stray current, and a good bonding system, can last up to 6-12 months or even longer.
We maintain a compliment of the most common anodes “zincs” onboard our vehicles. We replace anodes when they are around 50% degradation. Our anodes are priced at MSRP, plus our install fee. The install fee covers removing the old anode, cleaning the area, inspecting the area, and installing the new anode. Upon completion of any anode service(s), we take the old anodes away for disposal. Specialty or rare anodes are stocked at our head office. In the event a vessel requires a specialty anode that is not onboard our trucks, it will be sent out and installed on or around the next service.
Anode Pricing
Hull2Prop maintains competitive pricing on commonly required marine anodes.
General pricing for underwater anode replacement is based on the anode type, size, quantity, and installation requirements.
Pricing
Pricing can vary based on the specific anode, quantity, vessel, and installation requirements.
- $25.00 per anode: This price typically covers smaller shaft, bullet, propeller, trim tab, rudder, and thruster anodes.
- $35.00 per anode: This price typically covers larger shaft, bullet, propeller, trim tab, rudder, and thruster anodes.
- $45.00 per anode: This price typically covers all conventional plate anodes that are attached by thru-hull bolts to a vessel’s hull.
Buy Anodes Directly From Hull2Prop
Need replacement anodes but do not need underwater installation?
Hull2Prop sells marine anodes directly to vessel owners, boatyards, marine businesses, and other customers.
Customers can purchase anodes from us for self-installation, haul-out service, or installation by another marine service provider.
If you know the manufacturer, part number, dimensions, or type of anode you need, contact us and we can help with availability and pricing.
How Do I Know When My Anodes Need to Be Replaced?
Anodes should be inspected regularly for material loss and deterioration.
As an anode is consumed, its size and condition will change. Once an anode becomes sufficiently depleted, it may no longer provide the intended level of protection for the underwater components it is designed to protect.
Because anode wear varies between vessels and locations, visual inspection is the best way to determine whether replacement is necessary.
Hull2Prop can inspect your vessel’s anodes during routine underwater service and recommend replacement when appropriate.

Anode FAQ
All anode installations include removing the old anode, cleaning the area, inspecting the area, and installing the new anode. Upon completion of any anode service(s), we take the old anodes away for disposal.
Sail drives, feathering/folding propellers, I/Os, and jet drive anodes are common exceptions to our regular install fees. All of these drives and operating systems require additional time and labor to service anodes depending on the specific model and configuration.
