hi all,<br /><br />mariner ser#od994186 3f9<br /><br />Do to a misplaced manual could i please have the proper oil/ gas ratio(probablly 50:1) Is this an 86 or 99?.<br />Secondly, I used 50:1 last year and never experienced any problems, however, this year on my 1st trip out it would idle nice and run at 1/2 power but when opened up to full it would suddenly bog down and stal! After 3 times i got skeered and trolled in lol. I hope no critical damage occured!! Any suggestions are of course appreciated. ty
