I have just purchased a secondhand mercury 85hp, serial no. 9012052. I would like to know what the fuel/oil ratio is & also any other relevent info ie age, points to look out for.<br />thanx in advance, Graeme
That's right 50-1 ratio on the gas oil mix. It would be in your best intersest to get a manual and learn about your motor, clymer sells a great detailed manual. Good luck.<br />CU
