Don't worry about the 16" at the outlet, as long as it runs downhill I think you will be fine....just as long as it isn't submerged so it can drain and allow air back up.
Plus you could run that line the full length of your boat if need be, so up into a locker would be fine.
The higher you run it, the less water will come out of it and as long as it will drain back to allow air into the elbow to break a siphon...all is good. It just can't have too much residual water to drain back and fill your exhaust into your exhaust manifold....but that should be easy to see or calculate.
