Minn Kota is the only one that will work with H-bird.
I just installed the Ulterra on my 492v and ran it over the week end it's awesome. I have to do like most and rig a cable mechanism for my DI/SI transducer. I put the 80lb on my boat its 20-4 the TM has plenty of power to spot lock in white caps and wind. I tested it fishing 4 hours running it pretty much the whole time and spot locked atleast 5 locations one for an hour and it only ran down my Batts to 75%. I also ran it on 10 (high) for 2 hours straight in heavy wind and it ran Batts to 55%. I am pretty impressed with it so far.
If it were me I'd put the 112 on a 22 bay boat.
Better to chase some Dreams then to Die wondering!
