Okay, so I have a 2004 901 CDX/DC. I have always run a Mercury. First was an 2004, second was a 2000, 3rd was a 2011. All 200 hp. The trend here is I have not had a motor last for more than 4 seasons. I have it serviced EVERY YEAR by a Mercury Master Technician. I do fish quite a bit but am not a WOT racer every time I start the motor. I REALLY TRY to take care of my stuff! That being said, I just blew the head on the 2011 3.5 years after total rebuild. I am going away from Mercury if I end up re-powering with something new. Question is what do I move on to. Has anyone here run a Yamaha or Suzuki on their Nitro? Anyone have insight on cost and availability? I am really frustrated at this point. Yes, I can go with another rebuild, but have no faith in the longjevity of them anymore. Thought/opinions please. Thanks all.
