Mercury Twin Efi's - The Hull Truth

1intrepid1 · 05-27-2007, 07:44 AM

Have twin 1999 250 EFI's, they have been in the shop for water in the fuel problems three times. Each time the mechanic says something different at $85.00 hr service plus parts. Have spent over $ 4,000.00 on repairs from replacing both fuel pumps, filters, cleaning something called the rail, taking the injectors apart and cleaning them. Atleast that is what they said they did. Motors still run like crap. Now he is saying that it's water trapped between the injectors and some small screen that needs to be taken apart and cleaned and that he thinks that some of the injectors need cleaning. Want to go fishing but boat spending more time in shop than on the water. Motors only have 370 hrs on them. Is it time to get new motors, new mechanic, or both ?? Please help in Houston.

If I was you i would get out of there while you can afford to .How do you know that there is water in the fuel ? Pump about a gallon of fuel in a clear jug after the boat sits over nite the water will go to the bottom easy to see. ...Mike
