The ZTW SEAL Series is designed specifically for RC Boat applications, featuring a waterproof design. They are wrapped in either white or clear shrink wrap from the factory. We don’t get a choice. The 500A ESC includes two water cooling pipes as well as customized heat sinks. However, the 500A ESC does not offer a built-in BEC, requiring an additional battery pack to operate the servo. To protect the boat, the ESC offers a power reduction when too hot and an optional Low Voltage Cutoff. For more specific information, see the specs below…

Note: This esc will require an optional receiver battery pack or optional external BEC circuit. This ESC was designed to work in an environment where the ESC can get wet on occasion. Not for use underwater. OSE does not suggest using this item underwater!!
This esc is suggested for boats in the 60″ (1500mm) plus range. Because there are so many variables with each hull and installation it’s impossible to specify all the applications for this esc. If you have any questions about using this esc with your particular boat, please contact us before purchasing.
