I bought the RT178 last August and could not be more happy with the performance and with the service from the dealer. I have the Mercury 75 Optimax and it runs 40 mph when I am by myself and 37-38 mph with a passenger. It literally jumps out of the water. I had a minor problem with the Ranger stickers on the seats peeling and instead of replacing the stickers Ranger replaced the seats. It is a sharp boat and I have received many compliments from people in much bigger bass rigs. The extra money was well spent versus buying a Tracker.
