If the old seal is not hardened, melted, or cracked, you can re-use it. Otherwise spend your money and buy a new one.

If it is like the bellows on the larger engines, the tapered portion of the seal goes up--against the crankshaft.

Use some anti-seize sparingly on the splines before you install the lower unit.

Hello Frank, the old one is torn in half and have a person at go2marine.com looking for a replacement .. thanks for the info... the collar is still attached to the drive shaft rather snuggly ,, so i dont see a need to move it off the shaft.
