Title: Is the LEGO train motor 88011 waterproof?

  (Asked by: username_0 on 2023-07-07)
  
  My son has been building a LEGO RC boat and has added the motor ([part 88011](https://www.lego.com/en-gb/product/train-motor-88011)) from [this LEGO City Train Set](https://www.lego.com/en-gb/product/express-passenger-train-60337) to drive the turbines. He's pretty keen to try it out on water but I imagine the motor is probably not waterproof. I couldn't find any information on whether this part could be used underwater online so promised him I'd ask the experts here for advice.
  
  Additionally, I'd also like to know if anyone can attest to the waterproofness of the hub with the batteries from the same set (I think it's [this part here](https://brickset.com/parts/6370369/hub-no-4)). While he has stashed that away on the boat above the waterline, it might still get wet if things don't go as planned.

  LEGO's electric or electronic parts are usually not waterproof, with a [small](https://www.bricklink.com/catalogItemInv.asp?P=48064c01) [subset](https://www.bricklink.com/catalogItemIn.asp?P=48064c01&in=S) that was explicitly designed for such use in a [few](https://www.bricklink.com/v2/catalog/catalogitem.page?S=7244-1) [nautical](https://www.bricklink.com/v2/catalog/catalogitem.page?S=4669-1)-[themed](https://www.bricklink.com/v2/catalog/catalogitem.page?S=7906-1) [sets](https://www.bricklink.com/v2/catalog/catalogitem.page?S=7899-1) between 2004 and 2007. These motors feature no open contacts, integrated battery holders and gaskets along any seams to provide water sealing.
  
  The components you ask about have open contacts, no sealing - and even if they did, the radio waves required to operate them underwater would be greatly diminished by the physical properties of water to the point of unusability at even minor depths. They were not designed to be used in any kind of wet environment, including fog or rain. Surprisingly, I haven't found any kind of official warning to this effect in the building instructions, but if you'd like, I can ask a representative of LEGO directly.
  
  If you're really intent on using the motors near or in water, you'll need to either build a structure which guarantees that the batteries and motors will always stay above the water line (including any waves and spray) even if the boat rolls or capsizes; or build some kind of waterproof enclosure for them. Beware though, neither of these is an easy endeavour and any mistakes during design, building or operation could easily ruin both the hub and the motor. But there have been people who managed to achieve success with both of these approaches, so these are definitely doable - just with significant planning, engineering and tinkering and at no small risk.
