Other mistake: After stopped by the pirates and shooting them, Rambo accelerates his own boat again. The boat is driven by a rear mounted engine with a long shaft, with the screw 2 meters behind the boat. But turbulent water is exiting directly under the boat, which would suggest that the boat is equipped with a regular inboard motor, with the propeller under the stern of the boat.
