Raw Water

Why is it an outboard can circulate raw salt water but we cannot through aluminum automotive engines?
The new 4 stroke outboards are circulating raw salt water why cant we circulate salt water through the aluminum automotive motors we have now? I would like an exsact answer is it seals is it the typ of aluminum we use ect? The troubles with inboard outboards always seems to be with the risers and the whole heat exchange system in general lets get rid of it?
Outboards have a continual flow of cool water which is then discharged. In the process, salt will accumulate and, if not taken care of with fresh water flushes, block the water passages.
An auto cooling system is a closed system. The salt would solidify and block the passages rather quickly.
