Honda 50hp outboard gear oil drain screw

[ianmacneil]

I"m looking for replacement screws for the gear oil drain and wash port on the gear case assembly for my Honda outboard (BF50). The screws don't appear to be sold separately, only as part of the entire assembly. I started using an impact screwdriver to loosen them but previous years I didn't and they are beat up a bit. Thanks.
