I have an old boat trailer (1967'ish) that I want to replace the hubs on. It has the kind of wheels with no lug nuts. The boat that sits on it is a Sears, but I have no idea about the trailer or if its even the original. I took the wheel off, dug out the bearings. Both of them are 1 1/4" inside diameter, no number stamped on them. The seal is 1 1/2" inside diameter and its number is SL150. If I understand this right, I need a replacement hub for a 1 1/4" spindle but I am coming up empty. I've called a couple local trailer places and the guys dont seem to think thats a boat trailer dimension. Can someone point me in the right direction?
