Resealing Yamaha lower end?

Last summer I got a "rebuilt" lower unit that leaks from a dishonest ebayer. Due to lack of availability and it being middle of the season plus plenty of quick BS talk from the seller, I straightened the prop shaft ( was out .40!) and replaced the prop shaft seals. However, it still left a plume of oil wherever we parked so I pulled the boat out early. Does anyone have a video or source for resealing a lower so that I won't have this issue anymore. I'd like to either get on with the repair or put in for a legitimate new or rebuilt unit from SIM Yamaha.

No help on re-sealing. Sim Yamaha is a good source. Also SEI lowers are reasonable with a decent warranty.
