Are you talking about the several decades old non-viable plans? Perhaps that's not the best place to start...


A series DC motor relies on an air cooled commutator. There is no feasible way to waterproof the brush assembly. The best approach is to have splash guards on the bottom of the engine compartment and duct cooling air from a dry location.

A good approach for power cables is a lacquer spray on exposed conductors, with a fire resistant plastic cover that allows drainage. Heat shrink can be problematic for wet locations because it wicks and traps water.
