Has anyone ever used silicon hose for raw water side of cooling system ?
My concerns are that although reinforced, silicon does not have the rigidity of rubber hose and if the strainer became blocked whether it would suck its self flat. Also it does not have the puncture resistance of rubber hose, and where as the sealed system engine cooling failed it would only have may be a gallon or so of coolant. But if the raw water side failed it would flood the engine bay and possibly sink the boat in a short space of time.
Any thought or practical experience anyone?
