Water hose
Think of your engine water hoses in much same was as radiator hoses, more or less. The intake hose you're describing is reinforced NOT to give it strength per se, but to keep it from collapsing if pressure is on it or you bend it beyond the preferred no-great-than-30-degree-arc when snaking to/from a connection. The wire in water hose provides strength as a by-product, not by initial design.Also, to answer your question by way of example, I repowered by 78h30 last summer with a new engine and we ran dacron (looks like twine running in hose) reinforced, not wire reinforced, standard water hose. I suspect whoever ran your last supply hose happened to have a length of the wire reinforced stuff lying around and used it. I think you are generally safe either way you go. Just before to perform a "pre-float" inspection of your boat, i.e., seacocks, hoses and such and you should be ok.So, how about those tapered wooden plugs nicely attached to all your seacocks with a rubber mallet in a handy, yet prominent location in case a seacock breaks and you have to pound home a plug in a pinch? All your fuel lines in good shape? Fire extinguishers? Smoke/carbon monoxide alarms? Spare flashlights with extra batteries? Over the years, would you believe I've seen more people get into more problems with this kind of stuff than busted water hoses?
