🔌 Function

The tester applies controlled pressure or vacuum to a sealed sterndrive or outboard gearcase. Holding the test pressure confirms the integrity of propeller-shaft, driveshaft, shift-shaft and housing seals before lubricant is added.

Common signs of failure / service requirement:

• Gear lubricant contains water or appears milky

• Lubricant leaks from the propeller-shaft, driveshaft or shift-shaft seals

• Gearcase has been rebuilt and requires leak validation

• Housing impact damage or corrosion may have compromised sealing

• Pressure or vacuum will not remain stable during testing

📦 Condition

• New aftermarket replacement part

• Brand new

• Supplied in original or equivalent packaging
