a boat?
i was thing what kind of proportion u will use as brush-less motor can not be used

@TXJ_PROGRAMER i will use the small coreless DC motor

@MaxMadeGG is it water proff

@TXJ_PROGRAMER no absolutely not like any motor Is not water Proof because like you can put it in water and it will work the only problem is that it will damage the metal and it will become rusty and then it wont spinn well So for that you have to buy the silicone conformal coating or marine grease
