Hi guys, I recently bought an eFoil from China and have two questions I’d love your help with. I’m not a very familiar with DIY, so I’d appreciate your input.
1. Water in the battery chamber From my understanding, the battery chamber is supposed to stay completely dry. However, I often come back from a session with a ton of saltwater in there, leaving the battery half bathing in saltwater. The manufacturer claims this is an “acceptable amount of water,” but it feels like way too much to me.
I’ve checked for obvious leaks:
- Cable entries: Look properly sealed.
- Gore-Tex pressure valve: The bolt with the membrane seems fine and doesn’t look like the culprit.
- The Lid Seal: My guess is the leak is coming from here. As you can see in the attached image, the rubber seal looks really rough and uneven, not smooth. I suspect this is where the water is forcing its way through.
What do you guys think? And if it is the seal, what’s the best way to fix it?
The smaller chamber with water is normal, it’s to cool the ESC I think.

2. Water inside the motor housing / lower mast? Should water be allowed inside the bottom section that houses the motor? After rinsing off post-ride, I noticed saltwater weeping out from the seal connecting to the mast (red mark in photo) and around the metal piece at the bottom (blue mark), which I assume is for cooling.
The manufacturer said water in this part is normal. I’m skeptical because saltwater is no joke, and since everything is supposedly closed off, I can’t actually flush the inside with fresh water. Is this actually normal for some designs, or should I be worried? I’m thinking to soak it in fresh water and then properly seal all the sides, but I’m not sure if it’s a good idea.
Thanks in advance for the help!
