It sounds to me like its running out of gas. This could happen for a number of reasons. clogged fuel line, clogged filter, float in the carb not set correctly...Don't rev the motor up high unless you are under load, its hard on it. Its also running to cold, It should run around 180-190, most likely not causing your curent issues however.
Did you replace and/or check the float height when you had the carb off? Also, there should be an anti siphon check valve where the fuel line exits the fuel tank. This can sometimes get gunked up and slow the fuel flow. Running the boat using a temporary gas can could help eliminate the fuel suppy issues...
Others may have some trouble shooting idea as well.
