Late Summerization

[Le Bateau]

After our boat was winterized by an out of town dealer, we are just now getting to summerize. In the package of gear left by the dealer, we have 3 plugs.
one is the main drain plug, and two, well, they're identical, and unknown.
we have a Mobius LS.
Any insight is appreciated.

After some searching we also found that link!
there's one thing that we found on our boat that's not in the photos.
the winterization crew left a hose with a clip on it randomly hanging from the back of the engine. does it connect to the quick disconnect hose?
thanks!

I think you got your threads confused, so I'll just respond here. That is likely the oil drain hose. You can just clip it to the bracket used to lift the engine so it's out of the way.
