1999 225 Mercury EFI starting problems

[Spaceman]

I started my Mercury 225 EFI in the driveway and ran for a few minutes. Took it to the dock and put it in the water. It started for a few minutes then died,would not restart. Got home and same thing,it would pop on one cylinder and stop but would not start and run,confused!

Hey Spaceman, I'm having a similar problem, same motor, same year - did you find a solution that could help me (and others)? Thanks, dude!
