the price of the engine has nothing to do if you got plugged carb jets. You
need to figure out where the issue is... such as dirty fuel, gas tank,
hoses, etc. Why not have a marine dealer check it out?

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.
