my new, 1 yr old fl200 has worked flawlessly untill Saturday. while getting on plane it hiccuped and started running slow. will idle fine, just barely gets on plane and won't go over 4000 rpm. changed the fuel/water separator and the primary bowl filter on the engine, both were clean, but changed em anyway. made no difference. both of the better shops around here say it will be 2-3 weeks before they can get to it and we were planning on taking the boat to Rockport on the 28th. any ideas?

Whats an fl200? I would check to see if all plugs are firing and cylinders hitting first. Googled fl200 and it shows to be some kind of paternity test.

I'm not too familiar with that engine but since you replaced the filters my guess would be the Oxygen sensor....

it just happened all of a sudden while getting on plane. under warranty, but everyone's full up right now, so i might not be taking the boat on vacation. i could live with it as it is for a few days, but i'm scared it would hurt the engine. it's very slow to get on plane and i don't hardly ever run over 35-38 mph anyway.

As already mentioned, I would check for fire at all cylinders first. May only be firing on half which would explain lack of power. If that's the case, it would be an electrical issue.

Well, it was a bad throttle body. Steve at Meeks says it's the first one he's seen fail. lucky me. it's covered under warranty. he also said that i had carbon build up in the cylinders and is doing a de-carb. engine only has 84 hrs on it. is this normal. if it carboned up that fast, wouldn't that be a defect and be covered by warranty? he says i'm not running it hard enough. i cruise at around 4000 rpm. that seems hard enough to me.

You need to start adding a carbon cleaner.

Gary, could carbon buildup have been caused by the defective throttle body that was replaced ? Decarb being done & replace throttle body may take care of all of it. I still run sea foam through mine every 3 or four tanks. Older Rude 200.
