Is CrankCase waterproof?
CrankCase™ is water-resistant, meaning that it can tolerate splashed water, but it is not literally waterproof and cannot tolerate submersion. For enhanced protection from the elements, the unit’s case and backplate are precision-machined billet aluminum for an exceptionally tight fit. The backplate is secured by screws at six points. If you do suspect water damage, allow the unit to dry out over a day or two and re-power the system.
