The issue there is return to Europe.
The problem is that it should be below 1000 Euro. Once you export something over 1000 Euro from the EU things get complicated (actually all shippings the same day from the same sender are added). Over 1000 Euro the products have to be declared electronically using an agent and held available for customs inspection a few days before shipping.
Every day is a school day 
Might explain why an engine doesn’t get shipped out the same day.
But normally that doesn’t matter.
Why does the EU care what you are shipping out? It may be to do with the customs pre-clearance, where goods are cleared for the destination well before they get there and thus without being eyeballed, so you can understand the sending end may want to do spot checks.
OK.
After consulting with my usual shipping provider https://www.worldwide-parcelservices.co.uk I’ve sent it with them at a cost of £176.91inc VAT and insurance one way.
The box has been labelled as Peter has suggested, “TEMPORARY EXPORT FOR REPAIR, COMMODITY CODE 88033000” in big letters. The repairer in the USA has agreed to make sure that not only the invoice but the packaging is labelled with "Aircraft parts for overhaul and return to UK and
“UK HMRC export code: 88033000
UK HMRC import code: 8803300010” written on both the package and the documentation.
We’ll see what happens.
Overhaul cost is only $185.00 each!
You got ripped off on the shipping cost, for sure.
That is a DHL price, with insurance for about 2k value.
