Mercury 150hp EFI OUTBOARD shuts down
Posted: Wed Jun 12, 2019 7:13 am
Hello all, I have twin mercury (1999) 150 EFI saltwater series outboard, both starts and runs, however, one engine keeps shutting down, it re-starts easily runs for about 3 to 5 minutes, runs high then shuts down again, I've changed fuel filter & water separator to rule out bad gas, and still it keeps shutting down, any HELP?
