i recently purchase a 16ft champion bass boat with a 115 merc 98 i think. its the 4 cyclinder that idles on 2 cyclinders.the problem is when accerating at about 3000 rpm it hits a flat spot for a sec than kicks in a runs great after that.that flat spot is always there. went threw carbs a number of times and found nothing to be wrong.is this just a trait of that style motor r is there a fix.r is they a way to make motor hit on all 4 at ilde by maybe replacing carbs with air mixtures srews stump can anyone point me in a direction on fixing this problem r something im going to have to live with
