I may be acquiring a Sierra trail boss, what should I look out for aside from cracked or broken transmission and rotten frame. The engine has been swapped to a twin and was moved to the back of the machine, o assume because the exhaust wouldn't fit under the hump if it were mounted in front of the transmissions. I'm not finding much about these on line other than a few videos on YouTube and a vesely trans rebuild video "mini series" type deal. The plastic appears to be in okay shape other than being cut for the engine to fit. I haven't seen it in person just pictures a friend sent me. If they are worthwhile machines I'd like to try and get it going for my wife, it's been sitting uncovered for I have no idea how long, the pictures I have it's full of snow and ice. If these are junk or not worth fixing I'm still going to get it to make a trailer for my max. But fir now I'm just trying to find good info about these machines because if it's not too far gone I want to get it up and going for my wife to have her own amphib, I built/am building my max custom to me because I'm paraplegic and love being where the chair says I can't go. Attached are pics of my Max and the trail boss in question.
