Frequently Asked Questions 

Expert answers on professional hull cleaning, zinc replacement, and Florida marine maintenance.

Get a Free Quote

How often should zinc anodes be replaced?

Zincs should typically be replaced every 4 to 6 months depending on water salinity, stray current, and alloy type. Regular swapping helps maintain metal health and hull integrity.

Why do my zincs seem to disappear so fast?

High water temperature and nearby electrical leaks accelerate metal decay. Fast depletion means the anodes are working correctly, sacrificing themselves to save your expensive running gear.

Can I switch between zinc and aluminum anodes?

You should typically choose one alloy based on your specific water conditions. Mixing different metal types on the same vessel can cause uneven protection and lead to faster corrosion.

What happens if I forget to replace my anodes?

Neglecting replacements allows electrolysis to attack your propellers, shafts, and through-hulls. This leads to permanent metal pitting, brittle components, and very costly structural repairs.

Do you inspect the bonding system during a swap?

Every replacement includes a visual check of the bolts and contact points. Ensuring a clean, tight connection is essential for the anode to properly divert electrical current from your hull.
