It could be any number of things. Did it run even under load or was it rough? Did you drop any cylinders at WOT? Check fuel, carbs, timing as already mentioned. See if you can diagnose it as spark or fuel problem. If you put it in the water you can test spark under load. You might try choking it while trying to plane. If a float is stuck it would enrichen the mixture and make it better. My 250 was laying down similar to what you describe and I had a bad stator. Let us know what you find.

I checked compression and I have 4 cylinders at 116 and 2 at 120, so we're good there. I took out the sound box and sprayed a can of carburetor and choke cleaner on all three. The timing advance arm moves freely and I would like to check the ignition timing adjustment, but I have misplaced my manual and don’t remember the setting or procedure for this Merc 200hp.

try running the boat again and see if it picks up when you push teh key in for chaoke, it sounds like thte carbs need to be gone thru, spraying carb cleaner down thru the carbs dosen't do much, you have to dissasemble the carbs to clean them out properlly

Spare, if I understand you guys correctly, even if the motor ran and idled perfectly when I was by myself and the problem only started when I had an additional load (six people in the boat), I still could be looking at a fuel issue?

hwo long has it been since teh last time you ran the boat? Has it been run regulary? You could have some ignition problems going on, but it wouldn't care if it was loaded or not, it would run like crap either way, Sounds liek fuel, if it picks up rpm when you push in the key(applying the choke) its definatley fuel
