They'd lose momentum even with their initial burst of speed (recall that as a rule, Sonic doesn't tend to go full speed even when it would logically make sense to solve his issues) and sink like a rock, which is a death sentence when you can't swim. Hell, Movie actually DOES keep running across the water for a good long while, but it's the wave that ultimately does him in. Some versions, like Boom, can't even stand being NEAR water for too long.
I think the only versions of Sonic who have good demonstrations of handling water are Modern/Classic and Archie.
