Hello All.
Looking for some feedback from others that know a thing or two about these engines.
Boat is a 2004 320 DA, V drives, 4 blade props.
We had the mechanical survey/sea trial yesterday and the survey showed up some peculiar items in the ECM memory.
The mechanic suspects that the wiring harness needs to be replaced however, the boat ran perfectly during the Sea Trial.
Running gear needs to be cleaned but bottom was clean.
4 guys onboard with full water and half fuel load.
4500 rpm at WOT at 29mph
3700 rpm for cruise at 23mph
Here's a list of the codes that were shown. (Indicates results from Fault)
PORT ENGINE 614hrs.
Steer CKT LO (Stall)
SEA TMP CKT HI (Stall)
FUEL LVL2 CKT H (Stall)
PITOT CKT LO (Stall)
OVERSPEED
FUELPUMP RLY CK (Stall)
ECT OVRHT (STALL)
GUARDIAN
SEA PUMP PSI LO
STARBOARD ENGINE 618hrs
STEER CKT LO (STALL)
FUEL LVL2 CKT H (STALL)
PITOT CKT LO (STALL)
FUELPUMP RLY CK
OVERSPEED
IAC OUTPUT (STALL)
SEA PUMP CKT LO
I have both downloads if anyone is interested in seeing them?
Has anyone seen or had these issues on their boat?
If so, could this all be caused by a bad wiring harness or bad ECM?
Your input is greatly appreciated.
