hey everyone... i have a question and maybe someone has gone through this too. i have a 1988 four winns horizon 200 with a cobra 350... heres the problem... if i go WOT it will reach about 3500 to 4000 rpms sit there then start to kind of bog, the engine will slow down and once in a while it will back fire... it only does this at WOT... if i back the throttle off about 10% she runs smooth and steady and will run at about 35 to 40 mph... any ideas?! oh and by the way it has a mercruiser carb i dont know if that would cause it or not... i just got this boat after selling my carver... thanks everyone!
