!!!!!Please help water leak on lower unit oil!!!!!

[Aproline]

Hi I need help with my lower unit leaking water into oil the motor is a 1986 Yamaha 115hp. I have changed seals behind the prop and the ones on top under the water pump and still getting water in my oil. Does anyone knows what else it could be I paid a mechanic already and reinstall new the top oil seals. This problem is driving me crazy every time I go out I have to change my oil and I'm afraid something is going to break.

how is it the Yamaha tech did not pressure/ vacuum test lower unit to see where the leak was?

Pressurize to 15psi and dunk in water.

try 10 PSI and use a spray bottle with a mix of water and dawn dishwashing liquid.
there are 3 orings that could leak and 3 shafts with seals that could leak.
