I am working on my brother's 1988 bravo 1 and there was quite a bit of gear oil in the u joint bellow. My question is does the seal set behind the yoke, and if so do I remove the yoke or go in through the top?

You need a few tools but the drive shaft with gears comes out the front.
The yoke and gears are removed to gain access to the seal
Then everything is put back together IF "everything is within spec"

Then the preload is measured to ensure the nut is not over tightened

In short you need manual 11 to even begin, not counting the tools needed to remove and replace

The seal kit should be here tomorrow. Is the seal I'm looking for around the yoke itself or pinion gear/bearing assembly?

Not sure if you have already started into it . . . but . . . You drain down the gear lube at least a quart and then get the special tool to remove the large castle ring nut that surrounds the yoke.

With a firm pull the drive shaft/bearings/gear will come out. It is going to look like this . . .

Leave the top plate intact. IIRC, you are going to need a rolling torque wrench when you put it all back together. It is best to have the Bravo service manual handy.
