Hi, I have a problem with my 50 Hunter. After repeatedly firing at empty I found the emulsified oil in my engine 4JH4HTE. Some other owner of H50 has similar problems with the 4JH4HTE?

I would assume that you are "running" (not firing) your engine and found water in your oil. Sounds like a probable blown head gasket.
A couple of other things to consider: That engine has a direct driven sea water pump. Check the seal that keeps the sea water from getting into the crankcase. It would be weeping while the engine is running; another.... If the engine has been cranked a lot without running, you may have backed water into the crankcase from the exhaust side..?? another.. I believe the turbocharger on that engine is water cooled.. could have a cracked turbo case..??
Good luck with the search !

OK .My mechanic says it could be a problem related to poor installation of pipes. J have also a siphon break .
where are you finding the emulsion?
in the engine oil or in the exhaust?
It makes a big difference.

firing at empty?
If by "repeatedly firing at empty" you mean cranking the engine without it firing up and running then you've most likely filled the cylinders with raw water. That water has leaked down into the crank case causing the emulsion you see.
If this is the case, under no circumstances continue to crank the engine as you can bend a con rod. The engine will need to be drained, cause of not starting fixed and the oil changed several times.
Hopefully this isn't what you're talking about and it's something minor like a seal.
