eFoil maintenance guide
After-ride rinsing, seasonal inspection, and the wear items that need periodic replacement.
Salt water is corrosive and will degrade metal, seals, and electronics over time. A few minutes of care after every session keeps your eFoil reliable for years.
After every ride
Rinse with fresh water — the entire board, propulsion, wings, and all connection points.
Open the hatch and check for any water inside. Wipe dry if needed.
Rinse connectors — the Fischer/ODU data cable connections, phase seal areas, and LCS mount points.
Dry the board before storing — especially the hatch compartment.
Store the board on an eFoil Stand or a soft surface, deck-up.
Monthly / seasonal
Hatch seal — check the rubber seal around the battery hatch for wear or compression; a compromised seal is the main source of water ingress. Replace hatch tape from the eFoil Hardware Kit if degraded.
Latches and hinges — if the hatch doesn't close securely, replacement Carbon Fiber Latches, Latch v2 sets, and Friction Hinges are available.
Phase seals — the tri-color seals (green, yellow, red) protect the motor phase connections. Replace if worn, cracked, or not seated.
Propeller — inspect for chips, cracks, or bent tips. On LCS, verify the prop and tail cone are firmly clicked in.
Wing hardware — ensure all wing bolts are tight; vibration loosens them.
Mast hardware — verify mast-to-board bolts are secure. On LCS, check base plate screws (2.0 N·m / 18 in-lb).
End of season / long-term storage
Full rinse and dry.
Charge the battery to 40–60% for storage.
Remove the propulsion unit if storing long-term.
Store the board in a board bag.
Store the battery in a Battery Backpack in a cool, dry place — recheck monthly and recharge to 40–60% if it drops below 20%.
Wear items
Phase seals — replace annually or after impacts
Hatch tape — replace when adhesion degrades
Propeller blades — replace if chipped or bent
Data cables — inspect for corrosion; replace if pins are damaged
Deck pad — replace if delaminating or worn
