Strum box...haven't heard that in a while, although they are still a good idea. There's another term that isn't "sea chest", but contains the word "chest" that we might term a 'water manifold' today. That's what you get for reading a bunch of cruiser tales from the '20s to the '60s: a load of obscure sailing terms!
The Y-diverter idea on the engine intake is indeed a last ditch thing I would prefer to avoid, but it has its place as a way to winterize the raw water circuit by shutting off the seacock and putting a hose in a bottle of antifreeze. I do this with my Atomic 4, although I have to remove the thermostat and "top up" as it won't open in the 90 seconds it takes to drain the bottle, even if I pinch off a hose.
The PTO is the way to go for emergency bilge pumping, if only because it's possible to lose the 12 VDC at some point while still having the engine operating, and a PTO will run a purely mechanical pump very well.
I have a Rule 3700 for the main bilge aft of the engine (a deep well), a biggish Patay bulkhead-mounted manual pump, and a diverter for the Henderson manual pump in the head. I will be installing a second large capacity 12 VDC pump before we go, and a shower sump pump system of the very style that Omatako endorses.
