1. Did you run the motor at idle (same amount of time) in the water the same as when you flush the motor?
If not, try that. If you have the same problem, I would check the carbs or fuel pump.
Nope...in the water, I'm usually moving along, 3800 RPMs or so...no occasion for
idling, with what I'm doing.
2. Is the motor tilted different when you flush it vs. when your on the water?
No, she's basically "up & down" vertical...not in the travel-tilt lock mode, during flushing.
If so, possible problem with the float system in the carbs.
3. Have you pulled the spark plugs?
If the plug tip and insulator is black, the motor may be running a bit too rich at idle.
No, I haven't pulled the plugs...I can do that. Is idle mix adjustable, on these?
