Hi guys, I'm new here. My name is Jon and I've recently acquired a 1977 Johnson 85hp. I had an 84 90hp but it spun a crank bearing and tore alot of stuff up. I'm wondering if I can leave my current controller and type 479 cables on the boat and somehow convert the pre-79 motor type 400 on over to the type 479? On top of not wanting to reinstall another controller, the one that came with the older motor doesn't have the trim switch by your thumb, you'd have to install a toggle somewhere and I'm not very fond of this. Any help would be greatly appreciated! Thanks alot , Jon
