Brendan, the owner of Adak, stands on the port side of the engine. The engine is connected directly to the prop shaft, there is no transmission (marine gear). The engine is air started. Changing from forward to reverse involves stopping the engine and restarting it in the other direction. One cannot frequently change from forward to reverse and back again because it takes time to build up enough air pressure to stop and restart the engine. This makes for interesting boathandling.
