Leaving a jet ski (personal watercraft, or PWC) in the water overnight is generally not recommended due to potential risks and issues that can arise from prolonged exposure to water.
Here are the main reasons why it’s advised to avoid leaving a jet ski in the water overnight…
Risks and Considerations
- Hull Damage
- Continuous exposure to water can lead to water absorption and saturation of the hull, especially if the jet ski is not properly sealed or maintained.
- Over time, this can weaken the hull’s structural integrity and potentially lead to damage or deterioration.
- Marine Growth
- Marine growth, such as algae, barnacles, and other organisms, can attach to the hull, intake grate, and other components when left in the water for extended periods.
- If not regularly cleaned and maintained, this marine growth can affect performance, increase fuel consumption, and potentially damage the jet ski.
- Corrosion
- Saltwater is particularly corrosive, and prolonged exposure can accelerate the corrosion of metal components, including the engine, steering mechanism, and electrical connections.
- Freshwater exposure over time can also lead to corrosion if the jet ski is not properly rinsed and maintained after each use.
- Security
- Leaving a jet ski unattended in the water overnight increases the risk of theft or vandalism, especially in unprotected or public docking areas.
Best Practices
- Use a Lift or Dock – If possible, store the jet ski on a lift or dock designed for watercraft, which keeps it out of the water when not in use.
- Cover the Jet Ski – If the jet ski must remain in the water temporarily, use a fitted cover to protect it from exposure to sun, rain, and debris.
- Regular Maintenance Perform regular maintenance, including rinsing with fresh water after each use, checking for leaks, and inspecting for signs of corrosion or damage.
Long-Term Storage
- For long-term storage, especially in saltwater environments, it’s recommended that the jet ski be hauled out of the water and stored on a trailer or dry rack.
- If you are storing the jet ski for an extended period, properly winterize it to protect the engine and other components from freezing temperatures and corrosion.
While occasional short-term mooring or docking overnight may be unavoidable, minimizing the time a jet ski spends in the water can help prevent potential damage and maintain its performance and longevity. Regular maintenance and proper storage practices are key to preserving the condition of your jet ski over time.
