    Why do Mercury OB seem to rank so low

    Most OB polls I see on any boating site, Mercury is never the number one choice. Most always it is Yamaha. I have to say I am not a mercury fan, always been a Johnson/Evinrude. Now with the e-tec mixed reviews i have read and the dealer 140 miles away I don't think that is an option (like the...
