Julian, I checked for the humming this weekend and do not have it. Key on, motors off, turned radio down, and nothing. I can even go as far and say I forgot to turn the battery switches off for a full week and the boat started right up. Boat has no hum, no drain, etc.

The only thing that might help if you haven't found the issue yet is it might be in the tower somewhere creating this. Recall, I have the e-series boat but changed the tower over to a non.

Let me know if you need me to look at items for you to see if there are differences.

Nope...it is definitely coming from the throttle body....strange that you don't have it....and makes me concerned for those of us that do! I asked the dealer about it and didn't get an answer.....will ask again when I return for the AMP and Speaker replacement

I have it as well, assuming it is normal, as no issues with battery drain or any other problems that I know of
