Battery can be made watertight too with the help of the same silicone. everything else, just clean-up a bit after... that is all
You really don't want to immerse a motor in water. The armature plates are a mild steel which rusts up pretty fast. Ferrite magnets also corrode quickly. If you've got an aftermarket motor you'll probably rust up the bearings too. DC motors really aren't meant for water immersion.
