Hi Doug,

Under normal circomstances the motor in a scale ship doesn't get hot, if properly dimensioned.
If it has to work very hard, as may be expected when tangling with a caught fish, adding a cooling coil and brushtabcooling may be a good idea.
I would make a water pickup behind the prop and an outlet also under water facing towards the stern (creating suction), this way you'll have a pressureless cooling system that will always function, even when running slow.

I'd keep the hull closed intill you're shure it won't capsize under load, sinking her through the smoke stack isn't my idea of having fun...

Regards, Jan.
