What causes pontoons to pit?

Pontoons are a vital component of any boat, providing stability and buoyancy in the water. However, over time, these essential structures can become damaged and unsightly due to a process known as pitting. Pitting is a common problem that occurs when the surface of the pontoon becomes worn or corroded. So,? Here are some of the most common reasons:

1. Water chemistry

The chemistry of the water can significantly impact the condition of your pontoons. Water that is high in salt or other corrosive substances can cause the pontoon’s surface to break down, resulting in pitting. If you regularly boat in saltwater, it is essential to make sure you rinse your pontoons thoroughly with fresh water after each trip.

2. Chemical exposure

Another common cause of pitting is exposure to chemicals. If you frequently dock your boat in a marina or harbor where fuel and other chemicals are commonly present, there is a higher chance for the pontoons to become damaged and pitted. To prevent this from happening, ensure that you wipe down your pontoons regularly to remove any fuel or chemical residue.

3. Age and wear

Like any other part of your boat, your pontoons will age and wear out over time. Older pontoons are often more prone to pitting due to the natural deterioration of the metal. Pitting can also occur due to wear and tear such as rubbing against rocks, sandy shores, or vegetation. It is essential to inspect your pontoons regularly and keep them in good condition to prevent pitting from worsening or developing.

4. Exposure to the elements

Pontoons are continuously exposed to the elements, and this exposure can cause the metal to corrode and weaken over time. Exposure to the sun’s UV rays, rain, and humidity can all contribute to pitting and corrosion. To minimize these issues, you should keep your boat stored in a covered area when not in use.

There are many factors that can cause pontoons to pit, including water chemistry, chemical exposure, age and wear, and exposure to the elements. By being aware of these causes and taking the necessary steps to prevent pitting, you can enjoy a safe and fun boating experience for years to come. Regular maintenance and inspection of your pontoons can help extend their life and keep your boat looking great.
