Where to look for new HH engine

Had my crank break off right on the back of the harmonic balancer. Engine is getting pulled now for a rebuild but wondering about shopping for used or new replacement for it. Just don't know where to look really.

2009 LSV with 470 hours. Horrible timing, and like everyone else on here I love my boat. Crushed and such a random failure, boat ran great with no issues.

Thanks for any help.
