Is there something special about "humvee" diesels? When I was in the
air force (left the air guard 11 years ago) the humvee engines looked
just like the ones that were in our Blazers and Suburbans (of course
Suburbans were always referred to as "Carry-Alls" as I recall that's
what Chevy first called them). They had different air cleaners and
such, but they looked and performed about the same as the Chevy trucks.

I guess nobody would be impressed if someone had adapted a a Chevy
pickup engine for boats - it sounds better to refer to the "mil spec'd"
hummer. No?
