Check Engine when starting 2nd engine

[kamikazejoshua]

We have a 2011 AR240 that we've owned for three years. No problems with it really up until a couple of weeks ago. Sometime when we start the boat, we get a check engine light that blinks on the screen beneath the speedometer. This only happens when one motor is already running and started successfully. We usually start the port engine first and then the starboard. The second motor sounds like it is running kind of rough when the check engine light is on. Also, the RPM is stuck at 1000 and stays that way even when giving it some throttle.
We have so far been able to get the 2nd engine running normally by turning the key off and letting it sit until the little screen on the speedometer turns dark and the check engine is gone. This can take a couple of attempts though to get it running correctly. And the motor seems fine with no rough noise to it.
This whole ordeal doesn't happen everytime however. And I believe it has happened to both engines.
I have brought the battery to an auto parts store to test it and it had more than enough cranking amps. It still did it even when topping off the battery on a charger.
Any ideas on anything I can look for to help fix this problem?
Thanks

I would find a YDS system and hook it up. Your engine is throwing a code. You need to find out what code. Probably a sensor...

If you update your profile with your location, there may be a member nearby with one who would lend it to you...

I have the same issue, initially thought it to be battery related. Any solution / ideas?

Batteries

Especially if they are stock batteries in a 2014 in the heat of Dubai. Load test the battery (in the States the auto parts stores will do it for free for you--not sure about Dubai...).
