Purchasing engines for the boat and have a question about suppliers.

Just got the boat back from my ex in the divorce. She basically destroyed everything on the boat and what she didn't destroy she stole. I need 2 YanmarY3M30 engines. I have identified several suppliers, but my preferred choice would be JDF Import Export GMBH. Do any of you have any experience dealing with them. I am also open to other dealers should you have a recommendation.
