Seascooters such as Seabob, Sublue Navbow, SEANXT, Yamaha and other electric models are among the most sensitive water toys when it comes to winter conditions. Their motors, seals, electronics and lithium batteries are designed for performance in the water — but during the colder months, humidity, inactivity and salt exposure can quietly damage these internal systems.
Mallorca’s winter may look calm on the surface, yet the combination of moisture, temperature changes and salt in the air can create issues that only become visible when owners try to use their seascooter again in spring.
Understanding why proper winter care is essential can help protect both performance and long-term reliability.
1. Moisture Is the Main Cause of Winter Damage in Seascooters
Even when stored indoors, seascooters are highly vulnerable to moisture retention. Areas such as:
- battery compartments
- trigger housings
- magnetic sensors
- seals and O-rings
- motor ducts and nozzles
can trap small amounts of water after the last use of the season. Over the winter, this moisture can turn into corrosion, oxidation or degraded sealing surfaces.
These issues often remain invisible until the unit fails its first waterproof test in spring.
2. Salt Residue Continues to Cause Damage Long After the Season Ends
Most seascooter failures we see at the start of the season are linked to salt residue that was never fully neutralised. Even when the exterior appears clean, microscopic salt particles remain inside ducts and connectors.
During the winter, these particles attract moisture from Mallorca’s humid air, accelerating:
- corrosion of electronic contacts
- damage to internal metal components
- premature wear on sealing surfaces
Proper desalination and drying are essential to prevent these issues.
3. Seals and O-Rings Must Be in Perfect Condition Before Storage
The waterproof integrity of a seascooter depends almost entirely on its O-rings. Cold temperatures, inactivity and residual salt can cause:
- drying
- micro-cracks
- deformation
- loss of elasticity
A compromised O-ring is one of the most common causes of water ingress — and one of the most expensive failures to repair once damage occurs inside the electronics or motor.
Replacing worn O-rings before winter is a simple step that prevents serious spring-time problems.
4. Lithium Batteries Need Controlled Storage Conditions
High-performance lithium batteries are extremely sensitive to humidity and temperature changes. When stored incorrectly, they may suffer:
- permanent capacity loss
- internal corrosion
- reduced runtime
- uneven cell behaviour
To protect battery health, they should be stored:
- partially charged (around 50–60%)
- outside the unit
- in a dry, temperature-stable environment
- with clean, dry contact surfaces
Improper storage can reduce the battery’s lifespan or trigger faults when the season begins.
5. Why Owners Choose Professional Winterizing for Seascooters
At Nauti-Parts Mallorca, we prepare seascooters every winter under controlled conditions and with the correct diagnostic tools. Our service includes:
- full cleaning and internal desalination
- seal inspection and O-ring replacement when needed
- battery maintenance and health checks
- waterproof testing
- firmware updates for compatible models
- safe, dry indoor winter storage
- quick turnaround service (24/48h)
These steps ensure the unit is not only protected during winter but also ready for immediate use when the water warms up.
Seascooters are high-performance devices that require proper care during Mallorca’s winter months. Humidity, salt residue and long periods of inactivity can cause hidden damage that only appears in spring — often resulting in expensive repairs.
By preparing your seascooter correctly and storing it in a safe, controlled environment, you protect its performance, its longevity and your investment.
For professional winterizing or storage, Nauti-Parts offers expert service for all major seascooter brands across Portals Nous, Port Adriano and Santa Ponsa.
