pressure testing lower unit - what psi?

[BF]

Hi,<br /><br />I've got an '82 Merc V5 (150 HP) which takes water into the lower unit (after I have disassembled & reassembled it). I want to pressure test it to see if that will tell me where the leak is. How many PSI would you test with? I was thinking of 10-15. (?) <br /><br />thx<br /><br />Brent

Ten works,then vacume test with an equal amount.
