I have been looking into shipping an engine or two from Europe myself. Had much success with a local freight agent (Global Cargo Services) in shipping a fridge from Germany last year, so contacted him for info re engine shipping. When we did the fridge, we used the shipping agent as well as a broker to handle the import paperwork. We were surprised at how little it cost. As I recall, the import broker charged only about $75.00
Recent shipping quote for 2 engines on approved pallets was about $900.00, plus pallet cost. This is from a European location to a Vancouver freight depot here in Canada.
As they say, your mileage may vary, but this worked for me, and I will try it again.
Cheers,
Hugh
