    How do you test a lower unit for leaks.

    From what I've read testing should be done around 15 psi not 5 psi

    Johnson 30 hp lower shift seal

    Mission accomplished. Tapped a 5/16-18 threads into the shift bushing. Ran a threaded rod into the bushing through a block of wood on top of the gearcase housing. Ran a nut down the threaded rod to washers on top of the board. Tightened the nut and it extracted the bushing with seals. Replaced...

    Johnson 30 hp lower shift seal

    I saw someone tapped the bushing with a 5/16 - 18 course tap then ran an all thread into the bushing using a block on top of the gearcase with a nut to tighten so it acts like a puller. Think this will work?

    Yes oil was in lower unit when tested. 14 psi. No water in oil after running it for several minutes. Gear oil was empty when I bought the motor so maybe someone knew about the issue

    Johnson 30 hp lower shift seal

    Low hour motor. I barely pushed on it. In fact it leaked on its own when it was removed from the motor for water pump replacement. I noticed it leaking a good deal when re assembling. I'm wondering if a self tapping screw put into the bronze bushing then prying it out under the screw head?

    Thanks. Is there a schematic showing where to measure? Is it from the very tip down to where it enters the metal cover? And measure in neutral?
