I own an Evinrude ETEC 115 hp since 2007 , for saltwater in the south of France. So far I was very satisfied.
Unfortunately-and of course afer garabtee ending-, this engine has begun to stop without alarm message when running below 1300 rpm after about one minute low speed running. The local Evinrude agent has tried everything he could....but no alarm nor indication on the computer. He tried to chang EMM, spark plugs, cables to sparkplugs, capacitor, he disconnected sensors...strange statement : when disconnecting one cylinder, whatever cylinder it could be, the engine didnt stop anymore ! And more strange, Evinrude tells that such a motor must stop when running with only 3 cylinders !!
Technicians from Evinrude France have not been able to give the correct advice, nor technicians from Evinrude USA, whose answers were not easy to get.
I am very much disappointed from this lack of the constructor, who leaves a poor customer with his problem. Its also a deception for the local agent who had to order spare parts like EMM for trials without success !
If the computer doesnt know....nobody knows !!
Had anyone of yours to deal with such a stange thing ? Thanks a lot.

two things come to mind after reading your post. Not being there nor running the testing myself makes me offer suggestions for your mechanics to test.
One is to monitor the voltage on the 55volt circuit using a digital meter and looking for any variation just before or at the moment the motor quits. The Evinrude diagnostic program can also record the engine conditions while the motor is running and when it stops.
Another test is of the fuel system and to monitor the fuel pressures and for any air bubbles while the motor is running at ALL speeds and when the motor quits.
To determine if it may be a boat harness or control problem, temporarily hooking up a different control box and cable assembly will determine if the problem is at the motor or not.
There are various things that could make a motor stop suddenly, and troubleshooting is required to find out if it's an electrical or a fuel related situation.
The technician had tols me having changed the cables, the ignition coil, without any sucess.
The Evinrude reporting and monitoring system doesnt detect anything Wrong..
I'll check with the guy if he controlled something related to fuel pressure and possible bubbling
I know he checked also air admission control
When the motor quits does it start up again instantly or does it crank over for a while before starting?
If it cranks over but does not start, does the tachometer show rpm while cranking ? If not, the crankshaft postion sensor could be at fault as that is one of the few components that will stop a motor quickly if it does not generate a signal to the EMM.
Perhaps you can contact the European distributor for Evinrude to see if they can provide some type of assistance.
