I have a good friend and skipper, stuck in Hong Kong at the moment; he
is trying to refit a salvaged sailboat he found there and bring it
back to the states.

The boat's propulsion engine is a Ford Diesel inline normally
aspirated 6 cylinder with a "Lees" marinized fresh water cooling
system and is rated at 85 kw. It is pretty well trashed but the block
seems ok. There are a couple of similar engines in the boatyard as
spares; he is trying to determine compatibility.

The number 703F 3015 BA is on the block and 883F 8080 GAA is on the
head.

I was told it is probably a 2715E, with "T2" cast on the block.

The "spare" engines have the stamps 705F 6015 BA on the block and 823F
6090 GAA on the head.

He wants to know which of the following: flywheel, clutch, crank,
injectors, fuel filters, fuel pumps, water pumps, valves, and rods are
interchangeable between the different engines

Any ideas?
