Hi Dave, both the motor and the ESC have water cooling,
The boat does need a fair bit of speed as in the use case, speed is of the essence, it is a GPS controlled boat, i set the GPS cords and it goes there, all the technical side is working, from my testing at low throttles, however when i cranked it up thats when the ESC blew..
Luckily all the electronics are on a completely separate power supply π so they are all safe π
Do you have any links to products that you would recommend?
Regards
Ashley

Thanks for the reply, the boat was working and producing considerable thrust. for around 8-9 minutes, then fuzzed out.....
We had a 160A ESC -> link to the ESC that blew.
