We wanted the porthole in the forward end of the cockpit well to be usable for light and ventilation, so we put the engine controls behind a Beckson porthole in the aft end of the cockpit well. The Beckson porthole allows the engine controls to be entirely waterproof in heavy going when filling the cockpit with water. We found that by using a barrel nut as the knob, we could even fit the engine kill cable in the panel, behind the Beckson portlight.
The four gauges over the engine box are engine hours, water temperature, oil pressure, and fuel vacuum. With the exception of the hour meter, they are all mechanical gauges.
