Bill and El had twin Honda BF 40"s on their boat Halcyon that were replaced. They gave at least one of the used motors to someone on this site, but I can't remember who, off the top of my head, but might have been Charlie. Someone else will have details. Also, it shouldn't be too hard to find a used unit commercially, I'd suspect, but no luck on ebay. Good Luck!
