I have a Mercruiser 3.0L that when I drop the hammer it is not taking off quickly. Also sometimes at idle it dies. It did this the first time I took it out for the season this year. Its carburated and the carb. seems clean and not varnished. Could it just be old gas? I put in a pint of Marine Foam and filled the tank with Super unleaded (92 octane). I need it to be able to pull up an adult skiier.

Carb. is probably a little dirty. That's all it takes to throw it off. Accelerator pump may be worn. Plugs dirty?

Pull the top off the carb, replace the accel. pump, check the float level and fill the carb bowl w/SEA FOAM. Put the top back on it and pump the accelerator 2-3 times. Let it sit overnight. Internal carb parts will be clean in the morning. Start and adj. mixture, timing and idle--adjust to 650 but readjust in the water in forward tied to the dock."

"Your engine is running on the RICH fuel side. Can you adjust the mixture screw(s) by engine RPM or by "ear"? It needs to be a little leaner.
CLEAN the plugs.

W/the engine warm, VERY SLOWLY turn the mixture screw in until the engine begins to stumble; make a mental not of the screw position. VERY SLOWLY turn the screw out until it begins to stumble again; compare this position of the screw w/the first and turn the screw half way in between."
