I use a small barrel type pump to suck the oil out the filler neck,
it's slow enough, and messy, but works. A permanently plumbed hard
line from the oil pan drain and a good small pump, or a downhill
drain, if there is depth enough to your bilge, will do the job
conveniently, especially if you warm the engine oil before draining.

I installed this earlier this summer as per the installation I saw on
a friend's Atomic 4. As I was returning a rebuilt A4 into the boat, it
was a simple request to the rebuild shop to have them tap a 3/8" hole
into the lowest part of the pan. A couple of plumbing bits later and a
brass cylinder handpump gives me "white glove", five minute or so oil
changes conducted inside the engine compartment, and it was cheaper
than those vacuum style oil movers. They work well, but where the hell
are you supposed to keep them?
