So here's the whole story. I blew the powerhead in march of '19,  had a new head put on and at their recommendation had the air injectors rebuilt, new water impeller, lower unit gear oil and new plugs. Put the boat in the water and about the 2nd hr into the break in period it dropped number six cylinder. Sent that powerhead back in they said it was a fuel issue. Sent in the fuel injectors and a couple of them showed faulty on the print out. They rebuilt them and said all was good. ( I wish I would have had that done the first time )  they sold me another powerhead at a very reduced rate. Put it on and have been fishing it for the last year with zero problems.  

That's pretty typical.  Out of 9 Optimax (DFI) rebuilds I've only been able to determine the actual cause of 4 of the failures.   3 had water in the oil reservoir, and the other was an overheat meltdown (allegedly with no alarm, and no hard codes stored).  

From an outboard techs perspective those motors are a sonuvabitch.   Running problems seem nearly impossible for me to properly diagnose 80% of the time.   I fake it, guess, and get lucky about half of the time.  The others I give up on and send them to my most trusted Merc dealer....so it can be HIS headache instead of mine.  😊
