hello. i have a 2008 merc. 115 XL EFI S# 1B694253. with an occasional miss. i changed plugs and low end fuel filter. no help.miss started off and on about 1 yr. ago and now getting worse.still is not a steady miss.talked to shop and they said it was probably injectors. but is it possable it could be electrical? thats what it feels like to me. just a guess though. it does not seem to affect my top speed of 39mph/6300rpm/gps reading with a 13x15 4 blade prop.which i went to after reading the info. on your forums. thanks again.fuel has seafoam.
