i have a 1986 merc 115 L6, thats not right! spits and sputters above idle. i've replaced all the fuel lines and filters and noticed water "leaking" out of the #1 spark plug. i bought a new water jacket gasket only to have a tree fall on my truck so pulling the boat out isn't a option at tne moment, and i'm getting married in a month so money's tight. any help on what might be wrong or if i can fix it in the water would be greatly appreciated. is it possible to change the gasket in the lake or am i asking for trouble? thank you for any info you can give.
