V-34 Gearcase Vacuum Tester, Similar to the S-34 in appearance and operation, the V-34 tests for leakage in the opposite direction. Seals that hold pressure can still allow water to enter the gearcase. The V-34 checks for inward leakage.

As long as you own an out drive or Outboard you should have a good pressure and a vacuum tester. Stevens S34 and the Stevens V34 Vacuum tester are the best. Expensive but well worth it and way better than water in your drives.
Easy to use. Just screw into your drives fill or drain plug, use these tester to pump the required air into the drives to pressure and then vacuum test them. Hold pressure or vacuum as long as required, even overnight if you need. Works perfectly. Good investment for Professional or even DIY outdrive maintenance.
