98 FICHT Check Engine - Possible short

I have a 98 Evinrude FICHT 175 (E175FSXECS) that has been running fine until recently.  I got a check engine warning (SLOW was NOT activated).  The code is 37 - water in fuel.  I've replaced the filters in the engine and on the boat and checked the fuel.  It looked fine.  I had a dealer check it out and he said there's no water in the fuel.   I've disconnected the wire from the water sensor on the fuel filter on the engine and still get the check engine.  

 

However, I don't get the check engine warning when I run the engine with the boat on the trailer and use muffs.  The engine runs fine.  

 

Since I only seem to get the check engine when the boat is on the water I tried running the engine in a bin of water on my driveway and now I get the warning.  Could this be a grounding issue?  Any thoughts on how to locate it?  Could it be the EMM?  Any suggestions are welcome.

 

Thanks.

You have two courses of action to find the problem. Trace the wiring from the water sender to the connector on the ECU to check for chafing or grounding. If nothing is found, then there is a problem internal to the ECU.

 

If that is the case, you can send the ECU out for repair to one of the 3 popular shops that specialize in FICHT electronic repair. These repair facilities are not associated with nor are they recommended by BRP Evinrude, but they all have years of experience and good reputations for that type of repair.

 

CDI Electronics

Marine Computer Supply

DFI Technologies

Okay. Thanks.  I will check the wiring again to make sure I didn't miss anything before sending the ECU off for repair.

I am repowering my boat next week and will have a ECU available from my 99 ficht 225. i understand it is the same ECU in your model. it has been tested by evinrude certified mechanic. it would only need to be reprogramed for your engine.

Unfortunately a '98 FICHT has an aircooled ECU and the '99 has a completely different style water-cooled ECU. They are not interchangeable.

As a follow up, I had my EMM repaired and the problem has been resolved.  Thank you.
