I'm not sure how to help you as I do not know which speed controller you are using, but it sounds like its asking for transmitter input to set it up. Check your manual to see if they tell you how to set-up the esc, if at all. If it doesn't let me know which esc it is and I can help you from there. If it's an all in one unit (esc/rx combo) then it should be a plug and play unit and may require the help of the makers of the boat.
