I found a pretty extensive article on iboats.com called "How to install a SmartCraft system". The fella that posted it answered a lot of questions. Naturally anything pertaining to my setup wasn't there but I got a pretty good idea what was going on after reading it. I did like he did and just jumped into it with both feet and ended up with one left over cable. The thing I like about it most is that I can transfer it easily from one boat to another, There's a lot of information available with these engines but it doesn't do you any good if you're using anything smaller than a 40 horse. From what I've read this stuff has been available since 2004 or thereabouts. I must be out of the loop because I'd never heard beans about it. It's pretty slick though. There's also this other stuff called Mercury SmartCraft Active Trim. It's pretty nice too but expensive.
