I've never heard of this, but I've not really looked either. The 3/4" drain
is what I have. I added a scupper outside the transom (the Attwood scupper
flap fits over the exisitng thruhull), which kept me a lot drier, but I'm
still unhappy with the arrangment.

I think placement is probably ok. I'm not at all happy with the stock size.

My experience is limited but I've thought about this a lot myself. It never
occurred to me to try two drains, but I don't like the idea simply because
its more places for leaks, and you'll have some big centerline holes to
fill. My little drain has gotten clogged with debris a couple times so badly
that rainwater has filled up the sole like a tub. Like you, I intend to
replace mine with the flush-mount 1.5" hose cockpit drain and the
corresponding thru-hull with scupper. But I am planning on doing it in the
stock locations so I don't have to mess with blocking the old holes. These
drains and thru-hulls are so big i don't think anything smaller than a rat
could plug them.
I've also toyed with the idea of adding a seacock, but I dont think i will.
I figure if the hose were to breach and i was taking on water, the last
place i would even think of going would be down a quarterberth to turn the
seacock. Its a bit of a shame that the thru=hull is on the centerline, since
that complicates even getting a plug in there with the rudder in the way.
