Review: The right tool for pressure testing outdrives - Replaced O rings in two Bravo One sterndrives this spring and was able to use this tester to pump the required air into the drives to pressure test them. Held pressure at 15 pounds for 24 hours. Drives sealed well and had no water in them when oil was drained for the season. Worked perfectly. Good investment for DIY outdrive maintenance.
