I have a 1996 Mariner 9.9 that i use as a trolling motor. It has always run great, i have had a mechanic service it beginning and end of each season. the last time i was out it started puttering a little but not real bad. i get home and look at it and it has made a ton of oil (with gas). so i flush it several times and get it cleaned up then i go to change the lower unit oil and nothing came out, its empty. is there a correlation between these two? hopefully its not ruined. Thanks for any help.
