Have owned this 2006 Yamaha F150 with ~520 hours for 4 years - was running perfectly - last few weeks when I first start the engine it shakes and exhaust smells like it's running rich.
If I raise the idle to 1,200 wile in neutral, the problem persists.
After I run the boat for around 5 minutes at ~3,800 rpm, it would run fine, but today when I returned to the dock, it was shaking just a little and exhaust smells a little rich.
Haven't checked the plugs yet - wondering if this could be an injector problem. Thinking about checking the plugs and if there's a fouled plug, swapping the injector on that cylinder to see if the problem follows the injector.
Checked the Command Link - no error codes.
Any suggestions will be appreciated.
