Hi Guys,i am trying to find the fuel mixture for my 50hp mercury. The serial number i have. #9456469. i believe it is 100:1 although i have also been told 50:1. I assume it will foul the plugs if it has too much oil in the fuel.

50:1

The merc ignition is so strong it takes about 20:1 and idling to foul plugs.

100:1 will make scrap out of it in a hurry.

All normal mercs (fishin' motors) less than 30 years old take 50:1. Some are VRO (they mix it at a variable rate) and some racing stuff needs more oil.

hope it helps
John
