I have one but it's for a cruise. I don't know if it'll fit on the sonics but if it will then you can go ahead and purchase it off of me. I'll give you a good deal on it. I can't imagine that they're two different. It may take some modification that's up to you, but just letting you know I do have that. If a cruise one will fit on there in some way they can't be too far off as the motors are the same, but I just don't know where they're going to meet at the midpipe
