I am selling the latest model of the Waveshark efoil, V2. All I could find online is that it was released sometime in 2022.
When I went to pick it up, the seller said everything worked perfectly, but he wanted to check it one last time before I took it. I guess that was the moment when he burned the ESC. He didn’t know the motor was completely blocked due to corrosion in the bearing, which happened because the shaft seal broke. How do I know that? After connecting the remote to the efoil, the remote showed a whole lot of ESC errors.
Let’s start with the things that work:
The board is in good condition; the hollow carbon fiber board looks really nice.
Battery, charger, and remote are all in working condition.
Now, the bad stuff:
The motor had a rusted ball bearing and a totally destroyed shaft seal outside the motor, which was supposed to keep that bearing out of the water. After disassembly, I cleaned it up, changed the bearing, and added some mineral oil inside. There was a little bit of corrosion on top of the windings too, but after cleaning, it seems there is no actual damage to the wiring. Which, of course, doesn’t guarantee that the motor isn’t broken as well.
I bought the wrong shaft seal-the non-rotational part with the rubber seal is too big for the hole in the motor case. It should be pretty easy and cheap to find the correct part.
The bolts for attaching the fuselage to the mast broke. I believe the bolts fused/corroded to the mast, so you will have to use a drill to redo the holes or make them bigger and cut new threads.
Waveshark went out of business, so finding spare parts could be a problem. My idea was to try to repair this efoil, but I have neither the time nor the knowledge to replace burned components on the ESC-if that is even possible.
I would like to get 2,200 Euro plus shipping for everything. If you can’t find spare parts or manage to fix the ESC, you can always decide to replace the ESC, remote, and BMS in the battery, and you should have a pretty nice efoil for under 3,000 Euro.
If you have any more questions, want more photos or videos, or want me to check something specific, I am here to help!
Shipping only within the EU because of the battery.
