Before changing plugs or dumping that can of seafoam in the tank, get yourself some "powertune" from mercury. This is like Seafoam in a pressurized can that you spray into your carb throats. What you do with this is set your motor at high idle, then spray into the carb thoats...the motor will bog down but continue to alternate carbs. After a little bit, kill the engine then spray more powertune into each carb throat. Then...let the motor sit for about 1/2 hour or so.
Finally, take the boat out to the lake, and open her up...you will have a bunch of white smoke, but what you have just done is clear all the gunk out in one big blow. Most, if not all carbon build-up will be gone.
Once done with that, THEN change your plugs out.
Should run really smooth...
