Built in Brass



Hello Aniket,
i generally use brush dc perm motors for my scratch scale model boats, although brushless also are favoured if speed is a requirement.
but for a model scale craft between 24" to 36" I would suggest either one 12v dc 250gmcm torque & about 7500rpm, rated at 0.8A is about or in case of twin screws I would prefer 2 X 6v dc 100 gmcm torque 5000 rpm rated at 0.6A.

You mention that your batt is 1.3Ah but what is the voltage o/p ? If 12v then you could try a 12v dc motor specified above.
Photo of motor attached.

Regards
