I like the idea of a permanent valve.  Seems to me to be the best way to go.  Then all you have to do is to run a hose through the rear drain plug to the valve (assuming the boat is out of the water) and let it drain into a bucket or the like.    Will have to look into that for myself.

I installed an oil drain valve in my OMC V-6 a few years ago and in
retrospect it was a great decision.  Oil changes are trivial and not the
slightest bit messy now.  Before that I'd done it with bags several times
(making a small mess once and a huge mess the other time) and always
dreaded the oil change process.  It's been a busy day for me, so I'm going
to take the liberty of reposting one of my messages on this topic from a
couple years ago:

I put in an oil drain valve a couple years ago and it's a real time saver
over the plastic bag trick or making a mess in the bilge.  I'm using a
valve made by a company called Fumoto.  It's a brass piece that goes in
place of your oil drain plug.  It's got a metal valve handle with a
spring-loaded catch and a hose barb.

When I want to change the oil, I slip a few feet of 3/8 fuel line up
through the bilge drain (with the boat on the trailer) and onto the barb
and secure it with a hose clamp (perhaps not necessary, but I'm paranoid).
Then I flip the lever open and it drains right out - you can drain it
straight into jugs and not even get your drain pan dirty.  It does drain a
lot slower though through all that hose... [NOTE: Be sure to drain your oil

It's survived two seasons of boating [MORE NOW] without leaking and they're
certified by a bunch of manufacturers (and originally installed on many
boats and heavy duty engines), so it seems pretty reliable.

If you've got the 225 in^3 V-6 (155 hp) you need the F101N - 1/2-20
threads.  Be sure to get one with the "N" at the end - that means it has
the hose nipple.  I bought mine online from a place named Tewco near
Milwaukee (tewco@...) for $22.50 plus a few bucks shipping.

Here's the manufacturer's web site (you can also order them direct):
