Vacuum Tester - Gearcase

Gearcase Vacuum Tester

A gearcase that holds pressure will hold lubricant, but may leak in the opposite direction, allowing water the enter the unit.  Use this tool to test for inward leakage, assuring the unit is properly sealed.

Adapters are required to use this tester for gearcases other than Johnson / Evinrude or Mercury.  Call or email us for further details.

We also carry the Pressure Tester, see "Related Products" tab
