Is it waterproof … YES!

• 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.
