I just purchased a 2003 120 Open boat. I purchased it from a dealer, it's a brand new leftover. It's rated for a 15hp motor. I purchased a new 15hp Johnson 4-stroke seperately, and then realized it won't fit. The motor bracket won't fit over the aluminum transom bracket on the boat. With the motor clamps opened all the way, the motor won't slide over the transom bracket (transom and bracket are to wide). I called the dealer where I purchased the boat, and he was less than helpful. I've spoken with Triumph, who doesn't have an immediate answer, but has their engineers looking into this. Is anyone familiar with this problem, or have any ideas on how to correct the problem. Thanks!
