Hi Don. I have many friend fishermen who own OMC,HPDI,ETEC, and Yamaha motors that do not seem to be overly concerned with the potential disastrous effects of Ethanol to their motors. Is this a case that you have raised the flag for our benefit or do they not consider Ethanol as being a major problem? Not one has even considered changing fuel lines,etc, and few,if any, add any additives as a preventive. Is Mercury only sounding the alarm or is my small sample of friends not informed and should know better? Time for me to start to try to educate them? The boats range from the late eighty's to as current as 2008. I am really confused.
