You are not providing enough information for anyone to help you. On the running engine what are gauges reading, oil pres, water temp etc. Check the basics, are you getting spark to the plugs on the non running engine. Is there sufficient fuel getting to the engines. What maintenance have you done to boat and what if anything have you serviced recently. How old are the fuel filters.

[martin]

temps are ok, in the running engine, oil pressure ok, both engines rev down to 2500, more smoke than usual, on engine quit, alarms sounded. all checked water, oil, etc. and ok.

not on the boat to check others. like fuel filters, water separators etc.

Have you been back to the boat since? What is the current status? Can you get the engines started?

[martin]

yes, the engine started, seems that i have water in the fuel, what would be the next step to fix this and engine?

[witeagle]

let the tank settle out (don't move the boat for a day). Have the bottom 10-20 gallons of your fuel tank pumped out.

I had this same trouble from my 8.1L's I got the tanks clean but then had to clean the injectors. Even some of the best filters will let some trash go by if they are clogged bad enough.
