The gear oil for the outdrive would be in the lower unit itself.The trim fluid resevoir would be mounted inside the transom. The trim fluid if i recall is 5-30w oil (you had better check on that) and then gear oil for lower unit.

No, I did mean gear oil in the outdrive. There is a what looks to be a reservoir for gear oil. I found this

it looks to be close to what I have. Just not sure how to fill it, from the top or bottom.
