it is funny but also sad at the same time, that so many people ask where to "loot" motor because arrow doesnt point to it ... despite it being clearly stated in quest log:
"While you're out and about, could you stop by Booty Bay and ask our contractor for a spare zeppelin motor? I'm certain it's in his best interest if we make it out of here and deliver his goods. Markel Smythe's the name, he should be around the city's town hall at the docks."
