I have been having a series of problems with my 2002 Yamaha 9.9 4-stroke
outboard, mainly with blocked up carburetor jets. This season, I have had
to
strip them down three times to clean the jets. I have been putting Stabil
and
Mercury Quick Silver Cleaner in the gas tank, and that seemed to help for
a
month, until today, while out on Lake Michigan the engine stopped running
again. I don't know if all 4-stroke engines behave like this, all
Yamahas, or
just my particular engine. I expect better performance from an engine
costing
over two thousand dollars.




My 2002 T-8 has not had this problem. But I run a Racor or Sierra filter in
the feed line from the tank.
