Oil change on Mercruiser 3.0 alpha

[Aramasy]

i have a stern drive mercury 3.0 and I do not know how to add oil . Should I open the cover I highlighted with a yellow circle ? If yes should I remove the tube connected to it before ? I am quite novice and would appreciate your guidance. On the second picture there is the serial number and model. Thank you !

Ayuh,.... Welcome Aboard,..... Ya, that's the oil fill,.....

I believe it just pulls up, but might turn 1st,.....
The hose you can pull off, if necessary,....

It appears from the pics that someone has covered up the original information on the flame arrestor? Perhaps it's just a replacement from another motor but is a bit suspect.

As bondo states, the oil fill cap is noted correctly and most likely turns a bit to remove. Hose can be removed temporarily to allow cap removal

Thanks a lot guys for your reply and advice. If I understand correctly I have to turn a bit the cover and pull. Do you know by chance the procedure to winterize this engine ? On one of the videos on youtube the guy just pulls the engine drain hose (see picture) and the water is supposed to get out of the engine.
