I have an original MerCrusier Alpha One (Gen II) lower unit. Good condition, both mechanically and cosmetically; some light scuffs on the fin. Pulled from a '91 4.3l V6.
Well taken care of and has only seen fresh water.
$800 shipped, but feel free to make offers.
EDIT: This can also be picked up around the Chicago, IL or Lafayette, IN area to save a little.
