Hey guys,
I'm looking for a piston manufacture which allready have done oversize (stock replacement) pistons for Mercury 600/700 sci.
Mercury Racing have no plans to offer them, at least in the nearest future.
The current pistons are manufactured by a German company called König (OEM) own by Mahle, but even Mahle Motorsport (which I asked at the PRI) could't help here. . .

I assume your looking for inverted dome or "dished " pistons. JE and Ross make them for any size. Their top of the line pistons. Summit Racing has them.

Send one to Ross they can duplicate in any bore size you would want
