"Hi, I have twin 2003 Merc 4.3
"Hi, I have twin 2003 Merc 4.3MPI and continually get warning light and buzzers from both engines. Replaced both IAC valves, drained fuel tank, which is now clear of water, and had a complete service and diagnostic check which did not reveal any problems. I still get the warnings and have no idea what, if anything is faulty. Motors run OK. Is there a list of the warning codes. Such as 2 lights at one minute intervals indicates water in the fuel etc.
Thanks"
