I have a hose attached to the plug in the centre of the sump on one engine, not on the other. There I suck through an OEM tube beside the dipstick tube.
I get exactly the same volume of oil out of both, using a manual suction pump (has measurements on the side).
I doubt either location gets any heavy sludge, as that will be at the lowest point of the sump, likely a foot or more away from the oil removal location, due to slope of the engine mounting. I depend on the sludge, if there is any, being in suspension when I do my oil changes, always on a warm engine.

Just changed the oil for the first time myself. It was the easiest oil change over ever done anything I’ve owned before. Someone had installed a reversible pump. So I open the valve to the engine I’m changing. Sucks it dry in like 1 minute. Change the filter. Then suck the new oil into the engine. It’s a bit of a pain finding a place to take your old oil since there’s so much, but definitely not worth paying someone.

pumping old oil/recycle
29 years of elec pumps, hand pumps etc. best method consisted of an appr. 2.5 gal can with integral vacuum hand pump. evacuate the can by the hand pump and open the valve connecting flex tubing down the dipstick tube. extraction clean and easy. dump into larger can and repeat till done. only problem - i haven't seen another of these devices since.... (15 years +/-). originally purchased from west marine or boat u.s. when they weren't one firm.

How is that easier and cleaner than opening a valve and turning on a pump?

Our mechanic uses a vacuum pump he leaves connected overnight to extract all the old oil.

Overnight, I pump mine out in about 2 or 3 minutes. Overnight the oil will cool. I don’t want to mess with a 2 day oil change.

If you can suck it dry in less than a minute there can't be much oil at all.

Maybe 2 or 3 minutes. Not sure. It was fast. About 15 quarts or so. This plump is serious. Ill snap a pic next week when I’m there.

Best in this case is only an opinion. Everyone has their preferences.
Many prefer installed reversible, sump pumps.
And I agree.

It does sound odd. He removes the oil the normal way, but leaves the vacuum extractor connected overnight. Mechanic lives and works on the marina so he can, He often works at night, I got sent a pic of a chewed up impeller one night/morning at 0010. It does give a very clean refill over how I used to get it.
