Is 1999 DT100 a lemon?

[wportkid]

I bought a 1999 DT100 2 years ago and have had nothing but problems with it. Is this model just a bad motor? So far I've spent $1400+ at a Suzuki dealer for servicing (multiple visits)...cleaned the carbs, rebuilt the carbs, full tune up etc, plus many many hours working on it myself. Replaced the fuel tank and lines, add Stabil and Sea Foam to the fuel all the time. It runs rough, stalls when idling, coughs and sneezes at low to mid speed, drops RPMs at WOT, lots of unburned fuel / oil out the exhaust into the water, etc. etc. Does anyone out there have a DT100 that runs well? I've owned outboards for 50+ years and never had as many problems with one motor. I'm thinking I should just dump this motor and start fresh with a new one. Any feedback is appreciated. Thanks.
