The "suction" ability of most pumps used on boats for washdown/anchor rode
cleaning/water transfer/etc. is vastly overrated.
Just about any thicker wall hose works just fine.
With the plethora of hose types available, (go to a rubber/hose supply not a "marine" store,) and get better/more specific product at less cost.
Wire wound? with the assortments of hose to choose from the use of wire wound is mostly a thing of the past.
Applications for it on small/medium pleasure boats are very few, and then only if nothing else will work
, like a "difficult" section of engine exhaust
It's a miserable product, use only when nothing else will work
