Another variation.
I have a single engine with two intakes, close by but on opposite sides of the keel joined inside by a large curl of hose. THen to the single internal strainer, Perko.
I have never , yet of course, had anything clog the intakes even though I plowed through lots of stuff. over 30+ years.
The two intakes do have a coarse slot screen outside but the saving part I think is that the suction at each is so low that there is virtually no pull at the mouth of each through hull. I think it was a variation driven by the hull builders experience of building most of these things for the commercial fishing industry.
