Can't help you there as I have not worked on inboard engines.

I had twin marine diesels.
Only way to change oil was to use a vacuum pump.

If you have sludge then be thankful it is encapsulating the metal shavings. You are doomed.

There are manufacturers such as Mercedes-Benz who routes dipstick tube in such a way it is the ideal oil sucker. Just affix the extractor at the top and turn it on. No tube to insert.

Tested when I owned a Mercedes-Benz and found this technique pulled an additional 1/2 quart the drain plug missed. Never removed the 12 bolts on belly cover again.

That is exactly what I do with my current MB E350.
I am too old to climb under,.... and why would I?

Sucked out the oil via dipstick for years on my MB....heck even the dealer sucked the oil out. I rarely drain the oil from any vehicle via the drain plug unless I have to. My thoughts and no, I am not a professional mechanic, but have some common sense....

If I leave a 1/2 cup of old oil in the crackcase...big deal.
If there is a bit of crap in the sludge it will stay in the sludge or get trapped in the filter.

A straw/tube inserted to the bottom of the crankcase pan will suck any sludge up just as well as opening a simple drain bolt. Perhaps better.

A lot of things about Mercedes-Benz is Rube Goldberg: complex and wonderful for the sake of complexity. But now and then they do something brilliant such as route the dipstick tube to the very bottom of the crankcase for easy and complete oil extraction.

That linked pump must have been from one of the sellers Amazon kicked for cheating, the link doesn't work anymore.
