Transom Bracket - twin outboards

[JohnB]

Setting these up is trial and error, but I think your going to wind up at 3.5" plus or minus an inch. It also greatly impacts the performance of the boat, and the fuel economy so it is worth the time to get it right. Another symptom of the motor being mounted too low, or the trim being negative is the wheel is a little harder to turn. Maybe it is just my boat, but that is what I found.
