During a recent routine hull cleaning, I discovered severe cavitation burns near the propellers. The erosion was deep enough to expose the fiberglass beneath the gelcoat.
Cavitation occurs when propellers are out of tune or improperly matched to the boat. As the blades spin, they create areas of low pressure where v***r bubbles form and then collapse with significant force. Over time, these micro-implosions can erode the hull surface, leading to structural damage and costly repairs if left unchecked.
Regular bottom cleanings and inspections allow issues like this to be caught early. Even small irregularities in propeller balance or pitch can cause long-term damage, reduce efficiency, and increase fuel consumption.
Routine maintenance does more than keep your boat clean. It protects your investment.
