Any idea where to find seal kits for TRS drives (upper, lower and transom seals = the works). International shipping would be a plus.

You can get the seal kits from Värmdö Motor Teknik in Stockholm,Sweden http://www.motorteknik.nu/

I think that would be the best way for you to go since you are in Helsinki,
Just ship it with Viking or Silja line
