That makes perfect sense why it’s always activated. Your correct that we are a long way away from the EMM, I have a new relay that should be here in the next day or so. If I swap that out and she still gets hot then I’m assuming it’s gonna be the good old EMM. So I tried another quick test…ran her for 10 minutes in a huge cattle waterer bucket and ensured that the water stayed roughly 70 degrees with a hose letting it constantly overflow.(trying my best to simulate true lake conditions). After 10 minutes I shut her down. She started right back up and I ran her another 10 minutes. This time she went into her 3 finger salute mode…the EMM casing was around 115-118 based off my thermal temp gun. If it’s that warm on the outside maybe the inside of the EMM is getting quite a bit warmer and causing something like that “cold solder joint” that I’ve read about to disconnect. I had a fan setup so right after It wouldn’t start and I got my temps I turned it on to blow on the emm and back of engine. After 10 minutes she fired right up. I’m starting to think more and more that it might be the EMM. Dang…was really hoping I was gonna find something stupidly simple. But I’m learning a lot as I go, so that’s always a plus.

I’m also going to purchase the EV diagnostics that you recommend so I can stop pulling my hair out. I see that there is an Evinrude ETec on Amazon, will that also diagnose the Fitch or do I have to purchase once specifically for this motor. I would hate to buy one that’s not going to diagnose my engine.

I can only go by that write up from GEB our expert on the ETEC board and he indicates it will work on FICHT engines. Up to do to roll the dices

Some EV diag come with a CD ...like mine.... some come with USB pick what is best . Choose the one with the FDTI chip adapter to convert the PC USB port to signals for the test connector on theengine. (ususally close on top under the fw cover (on my ETEC anyway)


some... more $$$ come with a short boot strap cable used for brain surgery ( reloading special files) not needed for basic service and fault code look-up.

write-ups on that bug on FICHT EMM's does not always generate a fault code so don't be surprised.

Update: she is now back up and running. After thoroughly exhausting all other options, I did end up taking my EMM off and taking it to DFI technologies. Chet told me that he found some internal parts that needed to be replaced, basically what everyone seemed to think from the beginning. I took her on the lake and she ran like a new motor for a good solid hour, hitting all different RPMs and even WOT for a couple minutes. Ran like a top. Just wanted to say thanks for all the advise and help with getting me back on the water. Greatly appreciate your help!
