Does it look like this: http://www.ebay.com/itm/FOURWINNS-BO...-/201436318586 and this: http://www.ebay.com/itm/FOURWINNS-BO...3D201436318586

I'm embarrassed to admit that I don't really know what it looks like ..... it fell off and was lost before I got an opportunity to see what it really looked like. My recollection however was that it did not have a paddlewheel. What I was told by the technician attempting the repair was that there was a wire that was connected to the speedometer mechanism and when the unit fell off the boat the exposed leads of the separated wire came into contact with something and blew the fuse.
