I have a 1979 90 HP Mercury Inline 6 Outboard. It came on a 16.5' 1979 Crestliner Appolo Bowrider when I bought the boat last year, but I doubt it was the original motor. I have purchased an Autoblend system because the boat orginally had a fuel cell, but it was removed and I was mixing gas 5 gallons at a time (which sucked)... You can view the Autoblend at: http://cgi.ebay.com/ebaymotors/ws/eBayISAPI.dll?ViewItem&item=2489320899&ssPageName=ADME:B:EOAB:US:6 <br /><br />Do you know if this thing will work if I reinstall the tank and put this inline? My motor manual suggests not doing this on motors that were not equipped (but this one may have been, I don't know). The Manual also shows a simple installation of the wiring, red wire to positive, black to Negative!? It can't be that simple can it?!?!
