Gear Case / Outdrive Pressure and Vacuum Testing.

Are you wondering why a pressure test and a vacuum test are necessary?

Each shaft-seal area has two seals, back-to-back, or a newer style double-seal.                    

The outside seal prevents water from entering case.
The inside seal prevents oil from leaving case.

Leaking Oil or Water in the gear case will destroy the unit very quickly.
