I've got one 1987 Force 125 on my boat, and an identical "parts motor" I could get going again for about $400 or less. I'm just toying with the idea of getting a 21-24 foot "needs engine" boat off craigslist and converting it to twin outboards. Anybody have any experience doing that? I'm wondering where can you get twin Force controls? And what's it take to make one of the lower units counter-rotate?
