Another advantage of having the motor higher up is that you can then clear the well edges for replacing the steering cable. You should be able replace the cable by loosening the mounting bolts for the engine and forcing the motor to lean forward to get the extra clearance you need.

Re: Menemsha 16 Power to Reach Plane
The major negative factor in our maximum boat speed is that we currently run the large, 'high - thrust' gear case. In our usage this was a tradeoff worth making. A prior engine with the small gearcase reached about 34mph max speed.
