Merc 30hp EFI Issues
Posted: Mon Apr 23, 2018 6:59 pm
I have an 06 merc 30hp efi with remote steer. When the motor idles cold it surges and eventually stalls out. It will restart with no problem. Almost as if the low idle is set too low. If i warm it up i can keep it running on low idle but still surges every so often.
When i hammer down the throttle with a load it will run at full rpm for a few min then slowly start winding down to about 2/3 rpm with the throttle lever wide open. Seems as if its going into safety mode but no alarms being sounded by the motor.
I put brand new premium fuel in before first run this year, and always run with seafoam. It was run out of fuel, fogged, gear oil and motor oil changed before winter storage. I did the plugs, new fuel tank, fuel filter late last season as well.
Not sure if this may be a fuel related issue or a spark issue. Wondering if anyone has come across similar issues in the past.
Thanks in advance for any input to steer me in the right direction before i make an expensive trip out to a dealer.
