I can’t speak for that one specifically, but those 12 HP West Bend/Elgins are really fun motors to run. 12HP and I believe they weigh less than 60 pounds. Lots of power and pretty easy to work on, too. If came upon a good one and the price was right, I would snap it up. They are almost homely enough to be cool looking, too.
That one is the economy model. They also made a keyed version where you could lock them down into a lower HP to operate on HP-restricted water bodies or to slow them down if operated by a youngster.
