Just had a 650 Pfaff motor put in my 27' world class V bottom before the economy went to shit and am now stuck with the bravo 1. I was told I can basically use my bravo 1 case and rebuild the inners with XR drive components. Is this the best way for the money or are there some other select pieces I can just use to strengthen my drive? I am just trying to find the best way I can do this while not having a huge budget now days. Any ideas?
