Don- there is a 1997 150 merc efi listed in the motors for sale. Hit the forum today. Says part of a season on complete rebuild. Now knocking and down on one cylinder. If I shipped it to you, what would a ballpark rebuild cost be for you to rebuild it if we re sleeved or basically, started over from scratch on rebuild, assuming the worst? Makes me think, hmmm, might be interested in it.
