Yup... it’s got a leak. At least it looks clean, no water. Hopefully it’s just a seal and not a crack in a hard part.
Take your prop off. Might have fishing line in your seal.
Or maybe over filled
from where it is leaking , it may be the upper seal to the gear box .
looks to be a yamaha..
Pressure & Vac test also. Has it been serviced, is the oil level correct, water in oil. Check for metallics in oil while at it?
Upper seal where the shaft goes in? Only leaks when the outboard is tilted up? Maybe over filled with lower unit fluid unless the seal was damaged somehow
the upper seal under the water pump is most likely the leak...
or if you pull the lower unit and there is oil the the drive shaft dripping from above it is the oil pump seal....
been there done that on both...lol
Need more info. What outboard? 2 stroke or 4?
Looks like motor oil to me.
Check tightness on the oil filter.
If not that then it could be the power head gasket, crankshaft seal, and/or o'rings.
maybe your shift shaft seal is leaking, if you're lucky.

Haven’t used boat 3weeks was just noticed today. Didn’t see few days ago
That looks like crankcase oil, not lower unit oil.
Take off the lower unit and see. I had the same issue and it was the shifter seal in the lower unit.
My guess is shifter seal or drive seal. Those 2 are the usual suspects with lower unit leaks.
A sniff test should help determine if it is gear oil or engine oil. I have replaced the upper seal that Gary mentioned, not much more work than replacing the water pump.
Yea maybe, first smell it. Does it smell like your dip stick?
If so check your filter. If that's not it, pull all of the plastic off the motor and hunt down your leak. If it does not smell like your dip stick, you are going to have more fun.
Just hurt myself trying to smell my dipstick.
Great now California is gonna put warning labels on dip sticks "Not for oral...or rectal use."
