The 80's model walkarounds are XF series (Express Fisherman) The models are 200XF, 222XF, and 246/250XF. All of them are built on the same hull as the CCP models (Center Console Professional). They have a MUCH deeper dead rise than the 19-6 and 22-2 and are a totally different hull. The easiest way to convert one is to sell the walk around and buy what model you really want!
