It’s generally not recommended to leave a jet ski or any personal watercraft (PWC) in a lake or any body of water for an extended period.

Here are a few reasons why…

• Damage to Hull and Components – Continuous exposure to water, particularly in freshwater lakes, can cause corrosion and deterioration of the jet ski’s hull, engine components, and electrical systems over time.
• Algae and Marine Growth – Leaving a jet ski in the water for an extended period can lead to algae growth and accumulation of marine organisms on the hull, which may affect the performance and efficiency of the watercraft.
• Safety and Security – If the jet ski is left unattended in a public area of the lake, it could be stolen or vandalized.
• Environmental Impact – The prolonged presence of jet skis in lakes or other water bodies can have environmental impacts, such as potential fuel or oil leakage and disruption to aquatic ecosystems.

Instead of leaving a jet ski in the lake, it’s advisable to properly store it on a trailer, lift, or dock when not in use. This helps preserve the jet ski’s condition and reduce the risk of damage or theft. If storage facilities are limited, consider using a mooring cover to protect the jet ski while it’s docked or anchored in the water for short periods.

The goal is to maintain the jet ski’s longevity and performance while also being mindful of environmental and safety considerations.
