Is the ePropulsion Spirit 2 suitable for saltwater use?

Absolutely, the ePropulsion Spirit 2 is fully designed for saltwater use. ePropulsion uses aerospace-grade aluminum alloy as the base material, which is naturally highly resistant to corrosion. On top of that, the motor body receives two protective coatings: an anodic oxide coating (anodizing) followed by powder coating.

The battery connection uses corrosion-resistant metal connectors with PVD (Physical Vapour Deposition) coating over a stainless steel base—a harder and more corrosion-resistant finish than standard electroplating. The motor also includes a sacrificial zinc anode that can be replaced as it wears, providing additional protection for submerged metal parts.

To keep your Spirit 2 in top condition in saltwater:

• Rinse the motor thoroughly with fresh water after every use
• Apply a light coat of WD-40 to electrical contacts monthly during the season
• Keep battery and connector caps in place when disconnected
• Inspect and replace the zinc anode when significantly worn
