AMERICAN TURBINE SD-312 weep hole

[GoFastCDN]

The weep hole in the jet drive leaks water in pencil size stream when in water and engine not running when engine running no leak. Does anyone know what the problem is and how to fix it. It looks like there is a seal in the housing near the engine. Do you need to pull the engine to replace the seal. When I pump grease into the inner seal in the boat there is no pressure to the grease you can pump as much grease as you want.

I read on internet to puff air through weep hole and it might clear seal if there is item in seal face. Did it and heard a pop. After I tried to pump grease into zert. Could not add more grease as gun had pressure back. Any one experience the same?
