Leaving a jet ski in the water for extended periods can lead to several issues and potential damage, primarily due to exposure to water and environmental factors.

Here are some of the issues and damages that may arise…

• Hull Integrity – Continuous exposure to water can weaken the jet ski’s hull over time. Fiberglass hulls can absorb water, leading to delamination or blistering. Prolonged exposure to saltwater can accelerate corrosion, especially in metal components.
• Marine Growth – When left in the water, jet skis are susceptible to marine growth such as algae, barnacles, and other organisms that can attach to the hull and impeller. This growth increases drag, reduces performance, and may require more frequent maintenance to clean and remove.
• Mechanical Systems – Components such as the jet pump, intake grate, and steering mechanisms can suffer from exposure to water and marine environments. Saltwater, in particular, can corrode metal parts and degrade rubber seals and gaskets.
• Damage from Waves and Mooring – Jet skis left in the water are exposed to wave action, which can cause them to rock, potentially damaging the hull against docks, pilings, or other watercraft. Mooring lines can also cause wear and stress on the jet ski’s fittings and hull.
• Safety and Security – Leaving a jet ski unattended in the water increases the risk of theft or vandalism, especially in unprotected or high-traffic areas.

To mitigate these risks, it’s recommended to…

• Use a Lift or Dry Dock – Lifts or floating docks can keep the jet ski out of the water when not in use, minimizing exposure to water and marine growth.
• Trailering – Transporting the jet ski on a trailer and storing it on land when not in use is the best practice to protect it from water damage and environmental exposure.
• Regular Maintenance – Perform regular maintenance, including rinsing with fresh water after each use (especially in saltwater), checking and lubricating moving parts, and inspecting for signs of damage or corrosion.

By properly caring for and storing your jet ski, you can extend its lifespan and maintain optimal performance for enjoyable rides on the water.
