Mechanics in Honduras mainland and Roatan work for 1/4 of the labor price in The US.
Hondurans can always find a way to get something fixed.
However, you could start a new business in regards to marine engines. You still will have a huge set back that there are others that did the same.
There are A LOT of business opportunities in Honduras no doubt. Just need to see them and act on them.
Good luck I wish you well !!
