posted earlier on 1998 carb merc 150 offshore that had possible stator problems. after running thirty minutes or so and then idling for five minutes the boat would not plane out again until cool. Turns out all ignition and timing issues are fine. Fuel and filters are fine. mechanic has cleaned carbs and replaced needles and seats and adjusted floats and now boat won't plane even the first time. He says he thinks it may be excess pressure delivered by the fuel pump because of a broken sealing ring in the crankcase allowing crankcase pressure to be erratic. he says on this motor it is like each cylinder has it's own crankcase. This motor has under 75 hours on it. Does any of this sound possible? Any ideas on what else could be the issue? HHHEEELLLPPP!!!
