I went really low on the fuel consumption because the biggest outboard I ever owned was a 125.
I just looked up Nissan 140 HP, they drink 15gal/hr. Those twin 200's have to drink at least 35gal/hr.
Nothing makes sense in this story
This is a story told to Chinese by Hispanics, and then translated to English! It is a little surprising that they got the name of the ocean right.
Does sound a bit like "The Rime of the Ancient Mariner' though.
