Multi fuel mercury even runs on diesel in emergency? How is that possible? When diesel uses no spark..

Magic

With direct injection, you can do magic... but they make about 1/2 as much horsepower: http://www.mercuryracing.com/optimax-diesel-reporting-for-duty/

It only lights off without spark when enough heat through huge compression. Lean it out and spark it with a plug , runs like crap but runs I guess.

No, OptiMax.

My bad.

As time moved on and the military requirements became more defined – we set a course to develop a multi-fuel engine based on a conventional 2-stroke internal combustion engine design. The OptiMax JP (http://www.mercurygovsales.com/technology/optimaxjp.php)outboard is based on the 3.0 Liter V-6 OptiMax direct fuel injected, low emissions, 2-stroke engine. The 185 h.p. engine runs on JP5, JP8 and Commercial Jet-A fuels. The move to a multi-fuel engine based on existing consumer low-emissions 2-stroke technology is much more cost effective than alternative power sources. The OptiMax JP has been deployed and is serving military agencies in critical missions around the globe.

It's been done for years, back when I was in our portable firepumps used an Evinrude power head( I don't remember which engine, I think a 3 cylinder) that could run on jp5 or gas, and this is going back to the early 90's
