Re: i purchased a 2006 Baja H2X No no motor or lower unit theft recovery.
I have a mildly worked over low hour 5.7 complete less motor mounts, alt, ps pump, crank pulley and accy brackets in my garage that I yanked out of our Baja when we dropped in the 385 stroker. Considered a couple theft recoveries like you have purchased as a new home for it. Our engine is complete front to back except the items I noted. (AND NO IT IS NOT FOR SALE IN ANY SHAPE OR FORM - don't anyone ask) All the recoveries were missing about the same items - complete engine, outdrive, and cut wires everywhere.
The problem is (as has been pointed out) is the engine is really the least expensive part of doing this.
On your boat by the time you buy motor mounts, alternator, power steering pump, power steering lines, brackets for accessories, engine wiring harness, crank pulley, power steering cooler, oil cooler, flame arrestor, fuel pump, shift assembly, manifolds, risers, control cables (probably cut), coupler, starter,belts, sea water pump, outdrive, and whatever else is missing, plus fix what the thieves screwed up is you are into it way more than you could buy a similar boat ready to run.
For me, even with our engine and the few things we need it doesn't pencil out to for us even consider anything other than a boat that is complete with a bad engine and missing a drive.
Unless you find a donor boat that has virtually everything you need for a steal it's never going to work out financially.
