1994, Wellcraft - 5.7 Mercruiser: cruising for about 30-40 minutes at min wake to full throttle, at full throttle motor started popping and losing power, brought throttle to idle ran fine, went back up to 2RPM, again lost all power and died. After choking started up idled for short while again lost power and then had to be towed. Just had the alternator replaced and boat compression was given two thumbs up. I am thinking it's the fuel pump/system or carb? Any suggestions? My wife is losing faith in this boat - I have got to get it right!
