Hi all I have a 1998 merc 115 that was running awesome a couple weeks ago, but now it won't go above 4000 rpm @ WOT. Any ideas? SN 0g663741 I have tried cleaning carbs rebuilding fuel pump draining gas, refilling with 93 octane, new filters new fuel line & female quick connects. All with no change anything I may have missed? Also spark is good on all 4 &compression is 140ish on all 4 any help would be great.
Thanks
