I just purchased this motor, and after mounting it on my boat and turning on the ignition key, the unit on my center console beeped and the check engine light was on. I hooked up the serial cable to the motor and ran the diagnostic software from my laptop on it. I got 2 HARD codes 41 and 43 (these have to do with the Water Temperature switch and sending unit and associated circuits). Tried to clear the codes, the SW said they were cleared, but when I ran the test again, they were still there.<br />I ran the rest of the static tests (fuel injector, oil injector, spark at each plug and fuel motor), and everything seemed to be ok. I started the engine, and it ran.<br />I submerged the lower unit in a garbage can and filled it with water - ran the engine again, and the water pump appeared to be ok (water was chooting out the back like it should). I then removed each thermostat and ran the engine momentarily - water came out of the holes - that seemed normal. I replaced the thermostat covers, but left the thermostats out. Tried disconnectiog the WT sending unit and the WT switch - engine light still came on.<br />I tried to start up the motor a few hours later, and it now turns over, tries to start for a second or 2, then stalls - now I can't even get it started.<br /><br />Day 2 - I tried to start the motor today, and it started up - seems like the only problem I have now is the 2 HARD error codes. Reinstalled the 2 thermostats. Motor started and I ran it for 1/2 hour at 800 rpm.<br />Any help would be appreciated.<br />thanks,<br />Jack
