Bravo 1 leaking internal?
 

On my old boat the bravo 1 starting leaking oil out of the water intakes on the lower unit and after awhile out past the prop, so I replaced the lower housing because it was in bad shape anyway, but now I am thinking it must be an upper housing problem or seal because when I was filling it up it started to leak out the same place again. The drive is about early to mid 90's. Does anyone have any ideas? Thanks.:confused:

have you check to see if all of the shims and spacers have been correctly installed between the upper and lower units
