Is it waterproof … YES, it is!

• Watch the video RC MiniMono Boat – 3D printed Jet Drive UNDERWATER! After that, there was no water in it!
• If your print of the hull is good, it should be waterproof. But, if you want to be safe, you could still paint it with a thin layer of car clear coat. I tried both variants and it works very well.
• The drive shaft of the boat is sealed between two plain bearings with a lubricating seal.
• The cover is sealed with a 2mm cord of foam rubber or with a 3d printed flex seal
