I'm stumped - is there a part missing from the kit? On the front keel there are holes on both sides for bow thrusters, the instructions indicate Part 8 will fit over both holes. Part 8 is a small angled tube containing a single propeller, there's no way it reaches over both holes in the hull. It seems to me that there should be two of them (a port and starboard thruster). I'd be very grateful if anyone could confirm if a part is missing or, if not, how I'm mis-reading the instructions? Many thanks!
