2011 Merc 20hp 4 stroke stalls

My motor stalls often when i go from N to F. If i throttle up slow is stalls, throttle up a bit quicker usually is ok but not always. No issues other that that. Any ideas as to why? Has new plugs and thermostat. Thanks.

Is your motor fuel injected Robb?
Maybe try adjusting your idle speed up 50-100 rpms

Carburator. I just upped the idle a little, will havd it in the water tomorrow. Thanks.

Adjusted the idle up a little while on the water as opposed to while using flushing muffs. Seems to have done the trick. Thanks guys.

Sounds like a bit lean, if there is a idle jet turn it out a 1/4 turn at a time until it runs as it should.
