Well actually it would have to be a special design. Waterways for coolant to flow, etc.
Think like combustion engine cooling design.
The only submerged brush type motors I am familiar with are gas tank fuel pumps. Submerged in gasoline is a special case.

Submerged in gasoline with no air available does not usually a problem. But certainly a brush-motor in a gas tank is a special case. The various classifications of hazardous conditions versus electrical circuits will clarify that.
